When I am running the surface EI, I keep getting this error I have pasted below. How do I rectify this??

Hi @Vishwanath,

The (surface) Epileptogenicity process is working well. Check the following:

  1. Were you able to run without troubles the epileptogenicity tutorial with the provided data?
    neuroimage.usc.edu/brainstorm/Tutorials/Epileptogenicity

    In the shared error message it indicates that you are using SPM12 from a local installation instead from the the Brainstorm plugin, this is not a problem if using the latest SPM12.

  2. If you were successful in the point above, please provide more details on the data you are analyzing.

  • Screenshot of the Subject anatomy
  • Screenshot of the Subject functional data
  • Screenshot of the parameters used in the epileptogenicity process

SPM is up to date (v7771). I tried with multiple subjects an I am getting the same error. The volume EI works but the surface EI does not.

Ok it is working. I just removed all paths and re-added them and it was fine. Thank you!
