Other image stats

[Hannah Lindsey]

Hi! I just downloaded the Aug 26 version on my Mac, and it is no longer reporting stats for any additional images added to dataset. Specifically, I'm running longitudinal differential tractography, and I want to see the stats for the current dataset and the ses-02 images I added. The version I used yesterday (I think it was August 14?) still reported other image stats, so hopefully it's an easy fix??

Thanks!

Hannah

It should be a quick fix, have you check the console output to see if
it reads correctly?

Here's what the console says:

It appears that the images are loaded. Does *_tract_stat.txt file
shows metrics named ses-02_qa?

[Hannah Lindsey]

Nope! Just regular qa etc
