FATCAT_demo issues at Do_06

Hello all,

I was going through the FATCAT_demo and at Do_06_VISdti_SUMA_visual_ex1.tcsh I ended up with the error below.
I’m not sure what to do here

Hi, Patrick-

A) What OS are you using?

B) Does your afni_system_check.py show anything that needs fixing?

C) If you just run “suma”, does that open a GUI?


Hi Paul

I have OS 10.14.6

I don’t see anything special missing; well the R packages are missing.
Hard to tell what’s being used for this purpose, so I’ve pasted below the output of afni_system_check.py.

suma works fine on it’s own, I have the gui an can plot some data.

Hi, Patrick-

I assume that means that the $DYLD_LIBRARY_PATH isn’t being set in one shell. That has been the case in previous MB questions about that kind of message, like here:

From your system check outputs, it seems like that variable is set in your login (bash) shell. Can you just verify what the output of:


is from your terminal?

Can you copy+paste this in a terminal:

touch ~/.cshrc
echo "" >> ~/.cshrc
echo 'setenv DYLD_LIBRARY_PATH /opt/X11/lib/flat_namespace' >> ~/.cshrc 
echo "" >> ~/.cshrc

And also, to address the 2nd line of your “please fix” message in the system check, can you copy+paste this in a terminal:

echo "" >> ~/.bash_profile
echo "source ~/.bashrc" >> ~/.bash_profile
echo "" >> ~/.bash_profile

If you do that and open a new terminal, and then you try running the Do_06*.tcsh command, does that work, by any chance?


Hi Paul

All seems t be working fine now

thanks a lot
