小弟用Materials studio中discover模块作分子动力学，要求两个分子的质心距离随模拟时间的图，如何求啊，不胜感激。回复
小弟用Materials studiodiscover模块作分子动力学，要求两个分子的质心距离，如何求啊，不胜感激。 在MS里面选中一个分子，然后在“Properties”面板里选择“Molecule”，那个Center就是质心坐标。回复楼主解决了吗？我也想知道怎么求，可否告知？回复
楼主解决了吗？我也想知道怎么求，可否告知？ 我想求的是质心距离随时间变化的图。尚未解决，我放弃了。
你如果只求两个分子间质心距离，就先全选一个分子，然后在MS工具栏中找到一个centroid工具，点击即得到质心。然后同法找到另一分子质心。再在工具栏中找到Distance工具，就可以测量质心间距离了。:)回复楼主可不可以这样，吧你的每个轨迹都求一下，然后手动作曲线，原始方法、、、知道好方法请告知，楼主好人回复:pig:
同意5楼观点
可以把轨迹文件导入table，一个个求
如果会pearl编程的话可以计算机算
不过我不会pearl回复hbywl说的这个方法就可以我们一直在用

电话：021-[转载]用material&studio构建石墨烯模型
弄了好久，终于会构建石墨烯模型了，看了好多帖子，觉得都写的不是很详细，对于新手来说，有些困难，所以特发此贴。越简单的问题越容易被人忽略~
1、打开material
studio，新建一个工程，导入石墨graphite.msi（也可以自己build，然后添加原子）。
2、build-&make p1（目的是消除对称性，这样才能够删除一层原子）。
3、删除一层原子（选中原子-&delete）。
4、修改晶格参数：build-&crystal-&rebuild
crystal，设置方位角
5、构建supercell（方便掺杂，也为了好看）：build-&symetry-&supercell，构建一个5x5x1的超原胞。
surface（为了能够添加真空层）：build-&surface-&cleave
surface,(h,k,l)改为（0,0，-1）
7、添加20埃真空层（添加真空层是为了减小层与层之间的影响，至少20埃，大点没关系，最多是计算时时间长一点）：build-&srystal-&build
构建好后，模型如下：
接下来，在export导出*.p的文件，就可以用于vasp计算了。

编译之后，运行make install后，在C:/MSYS/local会生成bin、include、lib等文件夹。这样ffmpeg的编译环境就帮我生成了一个SDK,这个SDK在linux上用C来开发是没有问题的，我们需要使这个SDK在MS Visual Studio 开发环境中能用，编译的时候会碰到一大堆问题。我的环境是VS2008。
建立工程：
我们用ffplay验证我们的SDK，如果发现SDK问题，就可以得到及时的解决。建立一个ffplay的空工程，把ffplay.c，cmdutils.c，cmdutils.h，config.h导入这个空工程中,然后在VS2008中配置头文件目录和lib库目录(注意：ffplay需要用sdl，把sdl也加进入)
ffmpeg.c - 2.6.2:
cmdutils.h + cmdutils_common_opts.h + ffmpeg.h + config.h;
cmdutils.c + ffmpeg.c + ffmpeg_dxva2.c + ffmpeg_filter.c + ffmpeg_opt.c
编译并排错
下面是在VS2008中，编译ffplay出现的错误，有些错误时ffplay中出现的，有些事sdk的问题。
fatal error C1083: 无法打开包括文件:“inttypes.h”: No such file or directory
在vs2008下没有这个文件，实际上这个文件无非也就是一些整形定义而已，可以直接注释掉这个包含，自己创建这个文件，放到inclue/libavutil下，include改为#include&libavutil/inttypes.h&
fatal error C1083: 无法打开包括文件:“stdint.h”: No such file or directory
copy C:/MSYS/include下的stdint.h到libavutil中。修改#include&stdint.h&为#include“stdint.h”
fatal error C1083: 无法打开包括文件:“libavdevice/avdevice.h”: No such file or directory
用不着，直接注释
ffplay.cpp中报错
fatal error C1083: 无法打开包括文件:“libavcodec/audioconvert.h”: No such file or directory
fatal error C1083: 无法打开包括文件:“libavcodec/colorspace.h”: No such file or directory
make install安装的头文件不全，从libavcodec中copy这两个头文件
fatal error C1083: 无法打开包括文件:“unistd.h”: No such file or directory
许多在Linux下开发的C程序都需要头文件unistd.h，但VC中没有个头文件，
所以用VC编译总是报错。把下面的内容保存为unistd.h，可以解决这个问题。
/** This file is part of the Mingw32 package.
*& unistd.h maps&&&& (roughly) to io.h
#ifndef _UNISTD_H
#define _UNISTD_H
#include &io.h&
#include &process.h&
#endif /* _UNISTD_H */
int wanted_stream[AVMEDIA_TYPE_NB]={
&&& [AVMEDIA_TYPE_AUDIO]=-1,
&&& [AVMEDIA_TYPE_VIDEO]=-1,
&&& [AVMEDIA_TYPE_SUBTITLE]=-1,
};语法错误
VC的标准C++不支持这个赋值方式，我们改为
static int wanted_stream[AVMEDIA_TYPE_NB]=
error C3861: “rint”: 找不到标识符
rint函数是个四舍五入的方法，我们自己实现
inline long rint(double x)
if(x &= 0.)
return (long)(x + 0.5);
return (long)(x - 0.5);
或者添加新的定义：
#define lrint(f) (f&=0?(int32_t)(f+(double)0.5):(int32_t)(f-(double)0.4))
#define lrintf(f) (f&=0?(int32_t)(f+(float)0.5):(int32_t)(f-(float)0.4))
#define llrintf(f) (f&=0?(int64_t)(f+(double)0.5):(int64_t)(f-(double)0.4))
#define llrint(f) (f&=0?(int64_t)(f+(float)0.5):(int64_t)(f-(float)0.4))
#define log2(x) (log(x) * 1.) &
指示FFTSample
data[2][2*nb_freq];表达式错误
我们知道标准C++不支持动态数组。修改为
FFTSample *data[2];
malloc(sizeof(FFTSample) * 2*nb_freq);
data[0] = malloc(sizeof(FFTSample) * 2*nb_freq);
free(data[0]);
free(data[1]);
error C3861: “usleep”: 找不到标识符
VC中没有usleep，usleep是微妙级别的，所以需要把代码改为
usleep(is-&audio_st &&is-&show_audio ?rdftspeed*1000
Sleep (is-&audio_st &&is-&show_audio ?rdftspeed*1
指出&&& ap-&time_base= (AVRational){1, 25};语法错误。
还是标准C++不支持这种语法，修改为
ap-&time_base.num = 1;
ap-&time_base.den = 25;
建议用：av_make_q函数，更方便；
error C2054: 在“inline”之后应输入“(”
这是因为c不支持inline，我们把cmdutils.c改为cmdutils.cpp，把ffplay.c改为ffplay.cpp。
链接错误：
现在编译可以通过，但是现实一大堆库没有链接（好像有77个链接错误），把
avcodec-52.lib
avformat-52.lib
avutil-50.lib
swscale-0.lib
加进去还是没用，发现是我们用了ffplay.cpp，需要在ffmpeg所有头文件中加。
#ifdef& __cplusplus
extern &C& {
#ifdef& __cplusplus
这样就可以正确链接了。
最后可以正确编译出ffplay.exe。我们把include、lib和ffmpeg编译出来的dll打包，就可以发布了。
//新问题：
1：pollfd 结构重定义；
&&& os_support.h 和 winsock2.h 结构重定义，将os_support.h文件中的pollfd结构改为，如下：
#if !HAVE_WINSOCK2_H
struct pollfd {
&&&& /* events to look for */
&&& /* events that occurred */
出现 'class' : missing tag name
将void show_help_children(const AVClass *class, int flags);
改成void show_help_children(const AVClass *avclass, int flags);
cmdutils.c文件中： &可能编译通过，但是在vc的错误列表中可以看到这里需要修改：
void show_help_children(const AVClass * class, int flags)
& & const AVClass *child = NULL;
& & if (class-&option) {
& & & & av_opt_show2(&class, NULL, flags, 0);
& & & & printf(&\n&);
& & while (child = av_opt_child_class_next(class, child))
& & & & show_help_children(child, flags);
void show_help_children(const AVClass * avclass, int flags)
& & const AVClass *child = NULL;
& & if (avclass-&option) {
& & & & av_opt_show2(&avclass, NULL, flags, 0);
& & & & printf(&\n&);

在VC2008中编译ffplay，有一个全局定义：static enum ShowMode show_mode = SHOW_MODE_NONE;
但是enum ShowMode枚举类型是VideoState结构中的枚举类型，编译会提示SHOW_MODE_NONE没有没定义：
解决方法：
（1）：经enum ShowMode从VideoState中复制一份到全局；
enum ShowMode {
& & & & SHOW_MODE_NONE = -1, SHOW_MODE_VIDEO = 0, SHOW_MODE_WAVES, SHOW_MODE_RDFT, SHOW_MODE_NB
& & } ;//全局定义；
VideoState中的声明保留；
8： &&error LNK2019: 无法解析的外部符号 _av_frame_alloc；
这个问题一般是没有连接库文件或者添加cpp文件；
但是这里在ffmpeg中不是这个问题；
av_frame_alloc在frame.c文件中实现：
AVFrame *av_frame_alloc(void)
& & AVFrame *frame = av_mallocz(sizeof(*frame));
& & if (!frame)
& & & & return NULL;
& & frame-&extended_data = NULL;
& & get_frame_defaults(frame);
但是这个函数没有导出到我们的lib中；
但是我们可以用另一个函数代替：
AVFrame *avcodec_alloc_frame(void)，在utils.c文件中实现，头文件是avcodec.h;
AVFrame *avcodec_alloc_frame(void)
& & AVFrame *frame = av_malloc(sizeof(AVFrame));
& & if (frame == NULL)
& & & & return NULL;
& & frame-&extended_data = NULL;
& & avcodec_get_frame_defaults(frame);
有上述可以看出，两个函数的区别不大，只不过AVFrame *av_frame_alloc(void)设置内存为0而已；
av_frame_unref(frame); &-&&avcodec_get_frame_defaults(frame);
av_frame_free(&frame); -&&avcodec_free_frame(&frame);
9:&isnan函数，在ffplay.c中被应用；
但是在vc编译器中，无法找到实现，所以，&isnan函数可以修改 为_isnan, 包含头文件；
#ifdef _WIN32
#include &float.h& &
10：在编译ffplay的时候，我经ffmpeg中的相关的c文件设置为cpp文件，所以相关的头文件包含要添加extern “C” ；
相当于在cpp文件用ffmpeg，很好理解；如果是直接用c文件会简单一些；不过这里用的c++，所以还是用cpp方式比较好；
11：在编译ffplay完成后，启动程序，发现SDL_INIT错误：
解决方法： 屏蔽下面的话，我道理上应该自动条件编译屏蔽了，但是我用的ffmpeg2.0的源码这里还是会编译，所以在mfc上直接屏蔽；
#if !defined(__MINGW32__) && !defined(__APPLE__)
& & //flags |= SDL_INIT_EVENTTHREAD; /* Not supported on Windows or Mac OS X */
12：我用 VC2008 +&ffmpeg-2.0源码 编译，修改的地方还挺多，编译完成后，运行后直接退出，修改后，也没有声音，而且视频播放太快；
然后用最新的 VC2010 +&ffmpeg-2.6.2源码 + ffmpeg--git-a924b83-win32-dev +&&ffplay编译；
& & & （1）： sdk中可能少很多头文件，直接从源码中复制过来；
& & & （2）：之前直接修改ffplay中的源文件为cpp文件，在MFC中编译，现在为了省事，直接用ffplay相关的C文件添加到MFC工程中，设置后编译修改；
& & & （3）：可能ffmpeg中的几socket中的头文件和Windows中的socket头文件冲突，直接屏蔽ffmpeg中的结构体定义；
& & & （4）：然后&extern &C& ,extern main函数，模拟传入参数就可以调试运行程序了，这个没有问题；
& & & （5）：关于config.h文件，这个文件一般是在编译ffmpeg源码的时候会产生，但是这里为了方便，我直接放到这里；

AV_TIME_BASE_Q ： 修改为&av_make_q(1,AV_TIME_BASE)
需要编译ffmpeg.c2.6.2，需要compat文件夹中的头文件，所以可以直接将文件复制到自己的工程中；
cmdutils.c中会出现 _avresample_version等无法解析的外部符号等, 直接屏蔽&void print_all_libs_info(int flags, int level)函数中的内容；

小弟用Materials studio中discover模块作分子动力学，要求两个分子的质心距离随模拟时间的图，如何求啊，不胜感激。回复
小弟用Materials studiodiscover模块作分子动力学，要求两个分子的质心距离，如何求啊，不胜感激。 在MS里面选中一个分子，然后在“Properties”面板里选择“Molecule”，那个Center就是质心坐标。回复楼主解决了吗？我也想知道怎么求，可否告知？回复
楼主解决了吗？我也想知道怎么求，可否告知？ 我想求的是质心距离随时间变化的图。尚未解决，我放弃了。
你如果只求两个分子间质心距离，就先全选一个分子，然后在MS工具栏中找到一个centroid工具，点击即得到质心。然后同法找到另一分子质心。再在工具栏中找到Distance工具，就可以测量质心间距离了。:)回复楼主可不可以这样，吧你的每个轨迹都求一下，然后手动作曲线，原始方法、、、知道好方法请告知，楼主好人回复:pig:
同意5楼观点
可以把轨迹文件导入table，一个个求
如果会pearl编程的话可以计算机算
不过我不会pearl回复hbywl说的这个方法就可以我们一直在用

电话：021-[转载]用material&studio构建石墨烯模型
弄了好久，终于会构建石墨烯模型了，看了好多帖子，觉得都写的不是很详细，对于新手来说，有些困难，所以特发此贴。越简单的问题越容易被人忽略~
1、打开material
studio，新建一个工程，导入石墨graphite.msi（也可以自己build，然后添加原子）。
2、build-&make p1（目的是消除对称性，这样才能够删除一层原子）。
3、删除一层原子（选中原子-&delete）。
4、修改晶格参数：build-&crystal-&rebuild
crystal，设置方位角
5、构建supercell（方便掺杂，也为了好看）：build-&symetry-&supercell，构建一个5x5x1的超原胞。
surface（为了能够添加真空层）：build-&surface-&cleave
surface,(h,k,l)改为（0,0，-1）
7、添加20埃真空层（添加真空层是为了减小层与层之间的影响，至少20埃，大点没关系，最多是计算时时间长一点）：build-&srystal-&build
构建好后，模型如下：
接下来，在export导出*.p的文件，就可以用于vasp计算了。

编译之后，运行make install后，在C:/MSYS/local会生成bin、include、lib等文件夹。这样ffmpeg的编译环境就帮我生成了一个SDK,这个SDK在linux上用C来开发是没有问题的，我们需要使这个SDK在MS Visual Studio 开发环境中能用，编译的时候会碰到一大堆问题。我的环境是VS2008。
建立工程：
我们用ffplay验证我们的SDK，如果发现SDK问题，就可以得到及时的解决。建立一个ffplay的空工程，把ffplay.c，cmdutils.c，cmdutils.h，config.h导入这个空工程中,然后在VS2008中配置头文件目录和lib库目录(注意：ffplay需要用sdl，把sdl也加进入)
ffmpeg.c - 2.6.2:
cmdutils.h + cmdutils_common_opts.h + ffmpeg.h + config.h;
cmdutils.c + ffmpeg.c + ffmpeg_dxva2.c + ffmpeg_filter.c + ffmpeg_opt.c
编译并排错
下面是在VS2008中，编译ffplay出现的错误，有些错误时ffplay中出现的，有些事sdk的问题。
fatal error C1083: 无法打开包括文件:“inttypes.h”: No such file or directory
在vs2008下没有这个文件，实际上这个文件无非也就是一些整形定义而已，可以直接注释掉这个包含，自己创建这个文件，放到inclue/libavutil下，include改为#include&libavutil/inttypes.h&
fatal error C1083: 无法打开包括文件:“stdint.h”: No such file or directory
copy C:/MSYS/include下的stdint.h到libavutil中。修改#include&stdint.h&为#include“stdint.h”
fatal error C1083: 无法打开包括文件:“libavdevice/avdevice.h”: No such file or directory
用不着，直接注释
ffplay.cpp中报错
fatal error C1083: 无法打开包括文件:“libavcodec/audioconvert.h”: No such file or directory
fatal error C1083: 无法打开包括文件:“libavcodec/colorspace.h”: No such file or directory
make install安装的头文件不全，从libavcodec中copy这两个头文件
fatal error C1083: 无法打开包括文件:“unistd.h”: No such file or directory
许多在Linux下开发的C程序都需要头文件unistd.h，但VC中没有个头文件，
所以用VC编译总是报错。把下面的内容保存为unistd.h，可以解决这个问题。
/** This file is part of the Mingw32 package.
*& unistd.h maps&&&& (roughly) to io.h
#ifndef _UNISTD_H
#define _UNISTD_H
#include &io.h&
#include &process.h&
#endif /* _UNISTD_H */
int wanted_stream[AVMEDIA_TYPE_NB]={
&&& [AVMEDIA_TYPE_AUDIO]=-1,
&&& [AVMEDIA_TYPE_VIDEO]=-1,
&&& [AVMEDIA_TYPE_SUBTITLE]=-1,
};语法错误
VC的标准C++不支持这个赋值方式，我们改为
static int wanted_stream[AVMEDIA_TYPE_NB]=
error C3861: “rint”: 找不到标识符
rint函数是个四舍五入的方法，我们自己实现
inline long rint(double x)
if(x &= 0.)
return (long)(x + 0.5);
return (long)(x - 0.5);
或者添加新的定义：
#define lrint(f) (f&=0?(int32_t)(f+(double)0.5):(int32_t)(f-(double)0.4))
#define lrintf(f) (f&=0?(int32_t)(f+(float)0.5):(int32_t)(f-(float)0.4))
#define llrintf(f) (f&=0?(int64_t)(f+(double)0.5):(int64_t)(f-(double)0.4))
#define llrint(f) (f&=0?(int64_t)(f+(float)0.5):(int64_t)(f-(float)0.4))
#define log2(x) (log(x) * 1.) &
指示FFTSample
data[2][2*nb_freq];表达式错误
我们知道标准C++不支持动态数组。修改为
FFTSample *data[2];
malloc(sizeof(FFTSample) * 2*nb_freq);
data[0] = malloc(sizeof(FFTSample) * 2*nb_freq);
free(data[0]);
free(data[1]);
error C3861: “usleep”: 找不到标识符
VC中没有usleep，usleep是微妙级别的，所以需要把代码改为
usleep(is-&audio_st &&is-&show_audio ?rdftspeed*1000
Sleep (is-&audio_st &&is-&show_audio ?rdftspeed*1
指出&&& ap-&time_base= (AVRational){1, 25};语法错误。
还是标准C++不支持这种语法，修改为
ap-&time_base.num = 1;
ap-&time_base.den = 25;
建议用：av_make_q函数，更方便；
error C2054: 在“inline”之后应输入“(”
这是因为c不支持inline，我们把cmdutils.c改为cmdutils.cpp，把ffplay.c改为ffplay.cpp。
链接错误：
现在编译可以通过，但是现实一大堆库没有链接（好像有77个链接错误），把
avcodec-52.lib
avformat-52.lib
avutil-50.lib
swscale-0.lib
加进去还是没用，发现是我们用了ffplay.cpp，需要在ffmpeg所有头文件中加。
#ifdef& __cplusplus
extern &C& {
#ifdef& __cplusplus
这样就可以正确链接了。
最后可以正确编译出ffplay.exe。我们把include、lib和ffmpeg编译出来的dll打包，就可以发布了。
//新问题：
1：pollfd 结构重定义；
&&& os_support.h 和 winsock2.h 结构重定义，将os_support.h文件中的pollfd结构改为，如下：
#if !HAVE_WINSOCK2_H
struct pollfd {
&&&& /* events to look for */
&&& /* events that occurred */
出现 'class' : missing tag name
将void show_help_children(const AVClass *class, int flags);
改成void show_help_children(const AVClass *avclass, int flags);
cmdutils.c文件中： &可能编译通过，但是在vc的错误列表中可以看到这里需要修改：
void show_help_children(const AVClass * class, int flags)
& & const AVClass *child = NULL;
& & if (class-&option) {
& & & & av_opt_show2(&class, NULL, flags, 0);

在VC2008中编译ffplay，有一个全局定义：static enum ShowMode show_mode = SHOW_MODE_NONE;
但是enum ShowMode枚举类型是VideoState结构中的枚举类型，编译会提示SHOW_MODE_NONE没有没定义：
解决方法：
（1）：经enum ShowMode从VideoState中复制一份到全局；
enum ShowMode {
& & & & SHOW_MODE_NONE = -1, SHOW_MODE_VIDEO = 0, SHOW_MODE_WAVES, SHOW_MODE_RDFT, SHOW_MODE_NB
& & } ;//全局定义；
VideoState中的声明保留；
8： &&error LNK2019: 无法解析的外部符号 _av_frame_alloc；
这个问题一般是没有连接库文件或者添加cpp文件；
但是这里在ffmpeg中不是这个问题；
av_frame_alloc在frame.c文件中实现：
AVFrame *av_frame_alloc(void)
& & AVFrame *frame = av_mallocz(sizeof(*frame));
& & if (!frame)
& & & & return NULL;
& & frame-&extended_data = NULL;
& & get_frame_defaults(frame);
但是这个函数没有导出到我们的lib中；
但是我们可以用另一个函数代替：
AVFrame *avcodec_alloc_frame(void)，在utils.c文件中实现，头文件是avcodec.h;
AVFrame *avcodec_alloc_frame(void)
& & AVFrame *frame = av_malloc(sizeof(AVFrame));
& & if (frame == NULL)
& & & & return NULL;
& & frame-&extended_data = NULL;
& & avcodec_get_frame_defaults(frame);
有上述可以看出，两个函数的区别不大，只不过AVFrame *av_frame_alloc(void)设置内存为0而已；
av_frame_unref(frame); &-&&avcodec_get_frame_defaults(frame);
av_frame_free(&frame); -&&avcodec_free_frame(&frame);
9:&isnan函数，在ffplay.c中被应用；
但是在vc编译器中，无法找到实现，所以，&isnan函数可以修改 为_isnan, 包含头文件；
#ifdef _WIN32
#include &float.h& &
10：在编译ffplay的时候，我经ffmpeg中的相关的c文件设置为cpp文件，所以相关的头文件包含要添加extern “C” ；
相当于在cpp文件用ffmpeg，很好理解；如果是直接用c文件会简单一些；不过这里用的c++，所以还是用cpp方式比较好；
11：在编译ffplay完成后，启动程序，发现SDL_INIT错误：
解决方法： 屏蔽下面的话，我道理上应该自动条件编译屏蔽了，但是我用的ffmpeg2.0的源码这里还是会编译，所以在mfc上直接屏蔽；
#if !defined(__MINGW32__) && !defined(__APPLE__)
& & //flags |= SDL_INIT_EVENTTHREAD; /* Not supported on Windows or Mac OS X */
12：我用 VC2008 +&ffmpeg-2.0源码 编译，修改的地方还挺多，编译完成后，运行后直接退出，修改后，也没有声音，而且视频播放太快；
然后用最新的 VC2010 +&ffmpeg-2.6.2源码 + ffmpeg--git-a924b83-win32-dev +&&ffplay编译；
& & & （1）： sdk中可能少很多头文件，直接从源码中复制过来；
& & & （2）：之前直接修改ffplay中的源文件为cpp文件，在MFC中编译，现在为了省事，直接用ffplay相关的C文件添加到MFC工程中，设置后编译修改；
& & & （3）：可能ffmpeg中的几socket中的头文件和Windows中的socket头文件冲突，直接屏蔽ffmpeg中的结构体定义；
& & & （4）：然后&extern &C& ,extern main函数，模拟传入参数就可以调试运行程序了，这个没有问题；
& & & （5）：关于config.h文件，这个文件一般是在编译ffmpeg源码的时候会产生，但是这里为了方便，我直接放到这里；

AV_TIME_BASE_Q ： 修改为&av_make_q(1,AV_TIME_BASE)
需要编译ffmpeg.c2.6.2，需要compat文件夹中的头文件，所以可以直接将文件复制到自己的工程中；
cmdutils.c中会出现 _avresample_version等无法解析的外部符号等, 直接屏蔽&void print_all_libs_info(int flags, int level)函数中的内容；
