check the post "Has anyone checked the damping ratios from the channels in the .out files?" or search for "damp" & "channels"

thank you! But in that answer, you mentioned a readme file which I couldn't find there. Could you please tell me where I can get detailed instruction?

That posting redirect you to the post "Channels - tool to process outs files" for instruction to download the tool. The readme file is part of the release.

thankyou so much for the resources! However I am encountering the following issue. When in the dos window I type channels_chan_Pe_plt I get the following error: File "C:\Users\jsm20\Documents\code\Python\channels.py",line 139 in <module> ImportError: No module named Matplotlib

The ppt 'manual' says that additional python modules are needed: matplotlib, numpy, scipy, PyPDF2. With admin rights, in a DOS window, enter: pip install matplotlib. To run a damping calculation test, enter: channels chan_Pe_dmp

if I write pip install matplotlib,it shows "the system can not execute the specified program". What might cause this issue? is it compatible only with psse33 and python 2.7? Right now I was using psse34 and python 3.7
