Dear Chimera developer, I would like to perform the same operation on multiple files and I know that this can be done using a loop. However, I am not sure how to write the corresponding command or script. Therefore, could you please help me by writing a script that can perform the following operation? I have installed the 64-bit version of Chimera Headless Linux on my Windows subsystem. Thank you very much for your help! ################################### operation: File-> open -> abc.pdb Select-> structure->ligand Actions-> delete File->save PDB->rec_noH.PDB Actions->Surface->show Tools ->structure editing->write dms->rec.ms Actions->Surface->hide Tools ->structure editing->Dock prep->rec_charged.mol2 ##select the parameter of Unspecified(determined by method) File-> open -> abc.pdb Select-> structure->ligand Select-> invert (all models) Actions-> delete File->save mol2->ligand_site.mol2 ################################### Sincerely, Mingsong Wu mingsong_wu@foxmail.com
