Hello everyone!
For the first time I am trying to make some connectivity analyses on my resting state data.
I am facing an ‘out of memory’ error for each kind of connectivity analysis (correlation 1xN or NxN, coherence, etc…) I run, with standard options or custom ones. I tried selecting one scout or more. My workstation is provided with 16GB RAM and a good chipset.
I also tried to reduce the number of vertices in the anatomy folder, but I faced the same error. It only works with correlation AxB with a few scouts.
I thought that probably I make some mistakes in the way I proceed.
That is my pipeline:
- refine using digitized head points and warp default anatomy
- apply band pass and band stop filter, remove artifacts with SSP
- calculate noise covariance matrix from empty room record
- compute head model (overlapping spheres) and source model (2018, MN, constrained)
- process the source map with connectivity analysis.
I hope you can help me!
Thanks a lot!
