Error happening at "Network Metric Analysis"

[carolchang]

Hello, All,

I am running my system at catalina, with spm12 and matlab 2019b.
And at "Network Metric Analysis", it would encounter "dynamic library link" issue that "betweenness_centrality_mex.mexmaci64, 6): Library not loaded: @loader_path/libmex.dylib". The complete error message is as below.

Please help. Do I need to change the DLL setting in gretna? Thanks.

I met the same problem. Have you solved it?

Hey @ysy970 - I had the same issue with GRETNA (2.0.0 release downloaded from NITRC website, MATLAB R2021a). Our GRETNA error indicated that it was something to do with matlabbgl *.mex files, which are included in the GRETNA distro. I'm guessing that this older matlabbgl distribution is no longer compatible with newer MATLAB installations.

I was able to fix this by:

• Removing the matlabbgl folder from inside the GRETNA folder
• Install matlabbgl through MATLAB: Home panel > Add-Ons > "matlabbgl".

The matlabbgl folks remain quite active over on their github issues page, so I found this solution here. Other people with similar issues were able to fix it with this sort of approach (removing matlabbgl that comes with GRETNA, then downloading through Add-Ons or other sources).
