fail to convert matrix to cellranger h5 format convert matrix to CellRanger h5 format

[garfield-hu]

in section 10.1,
python scMatrix2CellRangerH5.py –m ./TEST -c example.filtered_feature_bc_matrix.h5 -o ./test.h5
I input fold path of ./TEST, which contains features.tsv.gz matrix.mtx.gz and barcodes.tsv.gz after -m parameter, however, it failed and the error log as follows:

scMatrix2CellRangerH5.py: error: argument -m/--matrix is required

so I changed -m parameter with just path of matrix.mtx.gz or matrix.mtx file, the error log remains the same. Dose anyone have idea ?
thx!
