I’m not quite sure why the
connectomestats command would take so long. The TFNBS statistical enhancement step is not particularly computationally difficult. Given you only have 27 inputs, I don’t think it’s the same issue as was reported for
There’s a test that you can do yourself that will at least get some way to figuring out where the problem is. Re-run
connectomestats but specify the “
none” algorithm. If that runs very quickly, then it’s the TFNBS enhancement that’s taking a long time; if it’s also very slow, then the issue is independent of TFNBS, and maybe there’s something that’s causing the GLM fit to take a long time.
I would also suggest manually checking those output files that the command will have already generated at that point. One way that TFCE can take a long time is if there are very large test statistic values generated, because the integration ends up counting from 0 to some large number in 0.1 increments (exponential integration steps would be better, but I digress); such a problem tends to be evident in the unshuffled data.
