Hi everybody, Not a very experienced python user here. I have sequencing data with 3' adapters I wish to get rid of, and am trying to install cutadapt for that matter. I tried on two computers, a mac and a linux; In both, the installation goes well - I downloaded several versions of the .tar.gz archives, extracted them, and used the terminal to go to the location of the unzipped folder, followed by entering the command: python setup.py install --user as instructed by the installation manual:

Installation seems to go well (no errors), but when I try to run the program (using the command: python cutadapt and so on...) I get the following error massage: can't find '__main__' module in 'cutadapt'

As I said, I tried three or four different versions of cutadapt, not only the last one; I also tried using the pip installer; The same error, however, keeps appearing. What am I doing wrong here?

Your help will be much appreciated, I'm getting pretty desperate. Thanks! Alon
