cellranger mat2csv (3.1.0)


WARNING: this matrix has 30585 x 4926 (150661710 total) elements, 94.197432% of which are zero.
Converting it to dense CSV format may be very slow and memory intensive.
Moreover, other programs (e.g. Excel) may be unable to load it due to its size.
To cancel this command, press <control key> + C.

If you need to inspect the data, we recommend using Loupe Cell Browser.
