若是没有明智地提前将原子名称区分好,或是即使用Select语法也无法选定特定的组,就只好通过建立相应的索引文件了。在distance与gangle等命令中所用的组往往需要选定两个位置,这两个位置应当在索引文件中成对出现。若是作为向量,则是从第一个向量指向第二个向量。同理,对于需要三个位置的组,则应三个为一行。下面是...

res and atom of -pbc. All three options give different results for triclinic boxes and identical results for rectangular boxes. rect is the ordinary brick shape. tric is the triclinic unit cell. compact puts all atoms at the closest distance from the center of the box. This can be useful ...

When eneopt = 1, this is the cutoff distance used for van der Waals interactions only. The particle-particle portion of the Coulombic interactions is computed with the cutoff of cutfd. nsnba (Default = 1)Sets how often (steps) atom-based pairlist is generated. decompopt (Default = 2)...
use-xy. To set the bin width and maximum distance to use in the RDF, use-binand-rmax, respectively. The latter can be used to limit the computational cost if the RDF is not of interest up to the default (half of the box size with PBC, three times the box size without PBC). To...
The RMSD at time t is calculated as the RMS of the differences in distance between atom-pairs in the reference structure and the structure at time t. gmx rmsdist can also produce matrices of the rms distances , rms distances scaled with the mean distance and the mean distances and matrices...
