Hi there, I hope this would not be late for this reply.

thanks for pointing this out. The error occurs when a large sparse matrix is internally being converted to a dense matrix. Actually, the dgCMatrix is a better choice. Considering the applicable for all method in CellCall, there may be a modification to fix this defect in next version.

Sorry for this inconvience.

Thanks !
