RE: conditions: matrix exceeds dimensions-problem
Hi Niels,
Sorry I am not exactly sure if I am understanding your question correctly. The scripts that import the information from SPM.mat files into the conn toolbox do not have a limit in the number of specified conditions. Perhaps the issue arises because your original SPM model is defined separately for each session (e.g. one single-session SPM model per subject and per session) instead of modeling multiple sessions directly (e.g. one multi-session SPM model per subject)? the toolbox scripts expect the latter (one SPM.mat file per subject). In any way, if you could give me a little more information on your error condition (e.g. are you entering this through batch scripts or with the GUI, how are multiple session modeled in your original SPM.mat files, what is exactly the error message that you get in the matlab command line) I will be happy to help you find out what might be going on.
Best
Alfonso

first of all: great tool. have been using it for single-subject analyses mainly but I would like to switch to group-level now.
I ran into a problem with the conditions in my spm-files: apparently, there is a limit to the number of conditions, which I was not aware of. my paradigm consists of three slightly different sessions. If I load them all, conn aborts with the above-named error. Any suggestions? I could of course run each session as a single "group" but this is not exactly helpful for my research.
cheers
