Matlab implementation of a source extraction and spike inference algorithm for large scale calcium imaging data analysis, based on a constrained matrix factorization approach.
No spatial downsampling is performed. Consider spatial downsampling if the field of view is very large.
No temporal downsampling is performed. Consider temporal downsampling if the recording is very long.
