7 years ago Hi @jennan The reason was purely computational because of the large number of components. I prefer to do some component screening prior to deconvolution outside the run_CNMF_patches, and then perform deconvolution on the sum C + YrA. But that's personal taste, you can have deconvolution inside the function. I wanted to replace the constrained_foopsi algorithm with the OASIS algorithm that solves the same problem but much faster, but haven't gotten around to do that yet.
Hello,
I was wondering why
run_CNMF_patchesdo not return spikes (returns zeros), even if the user setp > 0. It seems that this behavior is enforced in the code, see https://github.com/epnev/ca_source_extraction/blob/master/run_CNMF_patches.m#L265 and is there a specific reason for that (memory consumption when using the whole dataset ?).Thank you :-).
