各位老师好,我在用MCPB.py程序进行第一步操作(生成small和large model)的时候出现如下报错:
***Creating the small model...
It contains the residue 155-HID as sidechain coordinated.
It contains the residue 157-ASP as sidechain coordinated.
It contains the residue 246-HID as sidechain coordinated.
It contains the residue 274-CU as normal.
It contains the residue 275-SUB as normal.
Totally there are 67 atoms in the small model.
Traceback (most recent call last):
File "/public/software/apps/amber20cpu/bin/MCPB.py", line 643, in <module>
gene_model_files(orpdbf, ionids, addres, addbpairs, gname, ff_choice,

AtNum = Atnum[gatm.element]
KeyError: '1'
我相应的in文件是:
software_version g16
original_pdb 3w21-sub.pdb
group_name 3w21_SUB
cut_off 2.8
ion_ids 4236
ion_mol2files CU.mol2
naa_mol2files SUB.mol2
frcmod_files SUB.frcmod
large_opt 1
我的目的是想把SUB这个非标准残基也加入到small model中进行计算,但一直报错,有老师遇到过这样的错误嘛? |
