Colour maps sources

Hi Francois,
In response to your questions above,
"This is with the exact same list of files selected in Process2, right?"
Yes that is correct! I left the same files in process 2 and ran Test - Difference of means and had no problem with this process or viewing the results.

"If you can't open the files simultaneously, this means that you need to fix the time vector of the files first."
I can view the cortical activations simultaneously, no problem there. I ran the Standardize > Uniform epoch time process anyway but this doesn't seem to have resolved the issue.

I confess, this has me completely stumped. I have attached screenshots below as you requested.

Grateful in advance for any ideas!

Best,
Corinne
