CellBender can not remove the backgroud very well using the output of STARsolo

[JianhuaWang95]

Hello, I'm running CellBender using the output of STARsolo, however, I found that CellBender can not remove the backgroud very well. Only no more than 50 cells been removed. However, when I run CellBender using the output of CellRanger, the results are much better.

Here is the commond I used to run STARsolo:

STAR --genomeDir /pmglocal/
--runThreadN 10 --soloType CB_UMI_Simple --soloCBwhitelist /pmglocal/3M-february-2018.txt
--soloCBstart 1 --soloCBlen 16 --soloUMIstart 17 --soloUMIlen 10

--soloUMIdedup 1MM_CR --soloCellFilter EmptyDrops_CR --soloOutFileNames sample1/ features.tsv barcodes.tsv matrix.mtx
--outFileNamePrefix sample1/ --soloFeatures Gene GeneFull Velocyto SJ

Here is the commond I used to run CellBender:

cellbender remove-background --input /pmglocal/sample1/GeneFull/raw/ --output /pmglocal/sample1/GeneFull/raw/cellbender.h5 --cuda --epochs 75

The version of CellBender is 7.2.0.

Is there any suggestion?

Thanks!
