谢谢,我去了解一下这些广义系综方法。(以前只做过传统MD;SMD、TMD、umbrella samping之类随手玩过,但没发过文章,这些广义系综方法更不熟悉了。)
在Research Gate上面看到一个跟我的情况差不多的提问,有人这样建议选择reaction coordinate:
It is indeed easily possible to do this in Gromacs with essential dynamics.
Put open and closed configuration into one pdb file and make a PCA with
g_covar. This will give you exactly one eigenvector that connects open and
closed state. Then call make_edi to generate an input file for essential
dynamics. Choose the "radcon" option with your target configuration as
reference. Then start mdrun as usual but with an additional -ei argument.
See make_edi -h and mdrun -h for details. Hope that helps.
请您帮忙看看这样选择反应坐标合理吗?道理何在?多谢
