Dear Alfonso and CONN users,

I have been strugling for months with what seems to be a limitation of CONN

If I compare the Roi to Roi results between 2 diferent cohorts, corrected for cluster level, I run into a strange behaviour of the toolbox: I get VERY different results for even slight changes in the order of the regions in the connectome. Also, if i change the order i get different results that are not even remotely similar to the previous region order. In other words, you can either not see true results in one cohort or see 2 different results in one cohort. Then, only one of the regions order works in the second cohort. What leaves us with the very dubious task to assume which is "the right" one. 

There's more. If you remove the order of the regions, unfortunately thats no garanty that you will get the same results because even the order of the regions when you remove the order changes, is not always shown in a fix order.

Unless there's some procedure which sets some order in the Roi to Roi results, this limitations makes it, unfortunately, unreliable for publication, since any reviewer can ask " right, nice reuslts, but have you tried such and such organization of the clusters?"

Please could anybody help?

Best

Renzo
