I want to convert the dlg file into pdb format with command lines for batch processing, however, I have found that the corresponding documentions always teach us how to run convertion in GUI windows. And when I google the "command line for converting dlg file into pdb" , a web page enter link description here gives me a proper answer, however, there is Autodock3, which I can not find the corresponding one in Autodock4 and mgltools. So, where to download the older version of Autodock or which command lines can run the convertion.
