Dear Responsible, I am working on a script that should iterate through several structures, check the structures for clashes among all atoms, and eliminate the pdb in any clashes are found. Here is what I have worked out so far: # -*- coding: utf-8 -*- import os from chimera import runCommand as rc from chimera import replyobj import chimera # Specify folder folder_path = "/gporq3/store_0/usr/chiarini/chroma/chroma/" # String to be found search_string = "xxx" # List of files in the folder file_names = [fn for fn in os.listdir(folder_path) if fn.endswith(".pdb")] print("File trovati nella cartella:" + str(file_names)) # Loop on every file containing 'search_string' in the name for pdb_file in file_names: if search_string in pdb_file: pdb_path = os.path.join(folder_path, pdb_file) # Open the PDB rc("open {}".format(pdb_path)) # Calculates clashes rc("findclash") rc("wait") # Verify if any clashes are found clashes = chimera.clashClashList() if clashes: # If clashes are found eliminates the file os.remove(pdb_path) print("Clash trovati, il file {} C( stato eliminato.".format(pdb_file)) else: # If no clash, exit normally print("Nessun clash trovato per {}.".format(pdb_file)) But no analisys is done at all. I have been searching through the script page (https://www.rbvi.ucsf.edu/trac/chimera/wiki/Scripts) in order to found some clue on this function but so far I have found none. Could you help me on this issue?
