Hello Afniacs.

I am trying to analyze some multi-echo fMRI data and I've been stumbling over RetroTS.py. The first problem is that when I went to look at the help file online (https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/programs/alpha/RetroTS.py_sphx.html#ahelp-retrots-py), the following message was displayed:

Traceback (most recent call last):
File "/home/afniHQ/afni.build/pub.dist/bin/linux_ubuntu_16_64/RetroTS.py", line 28, in <module>
from lib_RetroTS.PeakFinder import peak_finder
File "/home/afniHQ/afni.build/pub.dist/bin/linux_ubuntu_16_64/lib_RetroTS/PeakFinder.py", line 29, in <module>
from pylab import plot, subplot, show, text, figure

This is essentislly the same error I got when I ran RetroTS. I also got the following error:

from pylab import plot, subplot, show, text, figure
ModuleNotFoundError: No module named 'pylab'

I'm running afni ver. 23.0.07 on a linux cluster ( Ubuntu 16.04.7 LTS)

My second issue is a question: How do I handle the number of slices per TR? The ME-fMRI data has 3 TEs (so there are 3 TEs/slice/TR) is the slice count n, or n*3?

Thanks for any help you can provide.
