Dear Responsible, I am trying to acquaint myself with "chimera --nogui --script" mode in order to automatize some pdb processing for a pipeline. I manage to search for pdb, to open the file, to select residues and to calculate COM for the selection. On the shell, I get the COM coordinates but I would like to print or store them to write them elsewhere. So the question is how can I print the replylog from shell to a text file, under the --nogui mode? I have tried with saveReplyLog but it doesn't seem to work...Any suggestions are appreciated. This is an excerpt from what I'm writing so far: import os from chimera import runCommand as rc from chimera import replyobj from chimera import saveReplyLog #change to the folder containing the pdb files os.chdir("xxx/yyy/zzz/ABC.pdb") def find_string_with_substring(string, substring): for s in strings: if substring in s: return s return None # list_files contain only the .pdb files list_pdb_files = [fn for fn in os.listdir(".") if fn.endswith(".pdb")] # specify the characters 'HLA' you want the filenames contain HLA_characters = HLA file_pdb_HLA = fins_string_with_substring(list_pdb_files, HLA_characters) print(list_pdb_files) print(file_pdb_HLA) nome = file_pdb_HLA replyobj.status(Processing " + nome) rc ("open " + nome) rc ("select :1.232") rc("measure center sel") saveReplyLog("~/reply-log.txt") Thank you so much -- Dr. Valerio Chiarini _Senior Scientist_ Proteins & Monoclona Antibodies Department b Takis Biotech c/o Tecnopolo Via di Castel Romano, 100 00128 Rome, Italy Tel.: +39 06-50576077 Fax: +39 06-50576710 Email: chiarini@takisbiotech.it Web: http://www.takisbiotech.it 196/03_ _Le informazioni contenute in questa comunicazione e gli eventuali documenti allegati hanno carattere confidenziale, sono tutelate dal segreto professionale e sono ad uso esclusivo del destinatario.
