Error with fit_gsfa_multivar due to large matrix size: ARMA_64BIT_WORD issue

[LifanLiang]

Thank you for you feedback. I suspect it is because there is not enough system memory to initialize a large matrix during the procedure. Please try to run this function with a subset of cells first, maybe just 1000 cells. If GSFA can run on a mini scale dataset, then it is most likely a memory issue.

Thank you for your reply.
I reduced the number of cells from 90,000 to about 50,000 and the function worked fine.
I was wondering if it could be expanded by changing the Armadillo settings, but I understand that it is a memory size issue.
Thank you for your time.
