unable to parse out UMI

[liuyang218622]

my data is 10x v3 data， I change the config file to umi length equal to 12 ，but it also reported that “unable to parse out UMI “，

Below is the command line that I write：
dropest -V -C 6000 -m /home/liuyang/01.example_script/02.cellranger/refdata-gex-GRCh38-2020-A/genes/genes.gtf -c ./dropEst/configs/10x_v3.xml ../01.rawdata/01.bam_file/sample1/sample1.bam
I got the error “unable to parse out UMI；
The 10x_v3.xml is:



10x

<barcode1_length>8</barcode1_length>
<barcode2_length>16</barcode2_length>
<umi_length>12</umi_length>
