Hello Chimera Team i have been trying to make a script for looping through a set of pdb files and get WebGL (.html) file as the output import os import chimera import Midas from chimera import exports from chimera import runCommand as rc # use 'rc' as shorthand for runCommand # change to folder with data files os.chdir("E:/files to work/") # gather the names of .pdb files in the folder file_names = [fn for fn in os.listdir(".") if fn.endswith(".pdb")] # loop through the files, opening, processing, and closing each in turn for fn in file_names: rc("open " + fn) rc("ac wb") rc("ac c2") htmlname = fn[:-3] +'.html' exports.doExportCommand("WebGL",htmlname) rc("close") This is the code I have been using in the script , but the output i get is not working , i have been getting 26kb files instead of 3-5 mb files and it doesn't show anything when I open it. can you please help me with the same as i am new to python code
