Problem with mean analysis for DTI-FA meta-analysis (SDMPsi)

We are tring to perform a meta-analysis on 18 datasets wih DTI-FA modality.

The mean analysis are stuck at the beginning of the multiple imputation step. It takes more than four days to perform mean analysis and the remaining time is always increasing (according to your tutorial, it's suppose to take few minutes). Do you know if the bug are reported from other researchers or do you know what we can do to resolve this?

Best regards,

Dear Justine, 

For what you explained, we are not sure what is exactly the problem of the software that produces that error, but is is tru that 4 days is too much for those computations. If you are fine with it, you can send us the data of you meta-analysis, and we can try to run it in debug to check what it is the real problem.  Send it yo my email:

Kind regards,
