Hi Sara,

Yes, it can be slow, particularly if the design includes regressors to accommodate repeated measures, many contrasts, spatial statistics, and if all ICs are tested.

All the best,

Anderson

Hi,

I am running dual regression on 52 scans from 26 subject to find an intervention effect on their functional connectivity. We have 51 components from group level ICA.
I let the command run yesterday morning, it finished the first two stages and created all the file for those stages by 7 pm. However, it's been about 23 hours that it has created only two files from stage 3. 

Here is the command that I am running:

I was wondering if it's suppose to take that long. If so, it means that my analysis would be finish in more than a month. 

Please let me know what i should do to expedite the process.

Thanks,
Sara
