I did exactly the same process than you and it doesn't work..

Ok gnwii, thank you for your message.
I've downloaded the new pyverchk3.py (and rename it) and delete the old.

This is what I get in the terminal:
cnormandin@Normandin-VirtualBox:~/seadas-7.4/ocssw/run/scripts$ pyverchk.py
Your default python interpreter is either too old or too new.
Do you have another python2 installation >= v2.6? (Y or N): Y
What is the full path to your python2 (v2.6 or greater)?: /home/cnormandin/anaconda3/bin/python
The following scripts have been modified to use /home/cnormandin/anaconda3/bin/python as the interpreter:

What I have to do after this?

Thank you very much,

Hello,

When I try to run update_luts.py (as in your example on the forum (https://oceancolor.gsfc.nasa.gov/forum/oceancolor/forum_search.pl?words=pyverchk3&user=&board=0&field=body&min=&max=&order=desc), it doesn't work. However, I've done all the steps writen on the post.

/seadas-7.4/ocssw/run/scripts$ update_luts.py --verbose aqua
  File "/home/cnormandin/seadas-7.4/ocssw/run/scripts/update_luts.py", line 50
    print "Mission needs to be one of:"
                                      ^
SyntaxError: Missing parentheses in call to 'print'

Thank you,
Cassandra

I think you have seen the "SyntaxError: Missing parentheses in call to 'print'" problem before.   It means a script intended for use with python2 has been
run with python3.   The pyverchk.py script was originally written to deal with different python2 versions.  It does this by editing the first line of
each Python script to replace "#! /usr/bin/env python" with a user supplied python2 path, e.g., something like "#! /home/seadas_user/anaconda2/bin/python".  The original pyverchk.py script doesn't work for users whose default python is python3 (e.g.,
because they installed anaconda3).  The pyverchk3.py script allows a python3 user to change the OCSSW python scripts to use python2.

When you ran  pyverchk3.py, you entered /home/cnormandin/anaconda3/bin/python.  This appears to be python3, not python2. 
Since you already have anaconda3, you can install python2 as an "environment" (see the Anaconda documentation), determine the path of
the python2 program, and run pyverchk3.py with this python2 path.  If you installed anaconda3 for use with seadas, you could just
remove anaconda3 and install anacaonda2.

Thank you gnwii for your answer again!
I've uninstalled anaconda 3 and seadas then I've installed seadas and anaconda2.
It works well on the command line and using the GUI.

Thank you!
Cassandra
