Hi!

I have used InstaCorr and 3dGroupIncorr before and it has worked great. I now experience some similar problems between the two functions and suspect something is wrong. Or, I just forgot how to use it.

lsb_a -release
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.2 LTS
Release:	18.04
Codename:	bionic

afni -version
Precompiled binary linux_openmp_64: May 29 2021 (Version AFNI_21.1.09 'Domitian')

Instacorr:
Opening afni inside a .results dirr.
Setting "anat_final" as underlay.
Clicking on Setup Icorr
Choose Dataset in the scond column: I choose errts.fanaticor and click Set. Then Set and Keep.
Terminal Output:

*+ WARNING: Forced switch from 'Original View' to 'Talairach View' [#1]
++ InstaCorr preparations:

By this stage I should be able to right click in one of the images, and take "InstaCorr set" and I should see correlations, like before. The button is click-able but nothing comes up when I press it or ctrl+shift+left-click.

3dGroupInCorr
I make a new directory, copy the anat_final to it
Then I run:
3dSetupGroupInCorr ../sub116-1/errts.sub116-1.fanaticor+tlrc. (only one file to test)
This gets me the files
Group.grpincorr.data
Group.grpincorr.niml
I then open afni
afni -niml &
In the same terminal I run
3dGroupInCorr -setA Group.grpincorr.niml
The terminal gives me:

3dGroupInCorr -setA Group.grpincorr.niml ++ 3dGroupInCorr: AFNI version=AFNI_21.1.09 (May 29 2021) [64-bit]
++ Authored by: Cox, the Mad Correlator

++ NIML connection opened from 127.0.0.1 (tcp:host:53213,AFNI_GroupInCorr_NIML)
 + GIC: OpenMP thread count = 15

But when I right-click in the image, or shift+left-click nothing happens.
If I go to define overlay, and select GrpInCorr and then Setup GICor it gives me a pop-up:
*** AFNI: ****
3dGroupInCorr
isn't connected!
Nothing happens in the terminal.

I tried this with no difference:
sudo ufw allow 53213/tcp

Do I forget a step in the AFNI-viewver or is somthing wrong? =)

Thanks!
