Mixcr postanalysis overlap

[singhd6]

Hi, I ran a commnad for postanalysis overlap with the following code in mixcr/4.7.0 and the results files are 1kb in size,


-> i further ran the following code for generating the v gen usage plot

then i received the following error: [singhd6@cc-dclrilog62 BCR_SEQUENCING_DS_REANALYSIS]$ mixcr exportPlots vUsage \

--color-key group \
"/mnt/beegfs/singhd6/Divya_data/vhseq/mixcr_analysis/BCR_SEQUENCING_DS_REANALYSIS//result.json.gz" \

--family-usage

[singhd6@cc-dclrilog62 BCR_SEQUENCING_DS_REANALYSIS]$
I checked the metadata files it is correctly formatted, could the error be because of the .jason file, also, I want to export the shared clonotype results and v gene usage for each clonotype

[singhd6]

one more issues i am having is:

Index 2 out of bounds for length 2
i checked everything but to my knowledge cant figure the error

[singhd6]

my metadata file for multiple dataset is:
sample group
A2-SUBJ066-IgM_S9_L001.clns IgM
A3-SUBJ018-IgM_S17_L001.clns IgM
B1-SUBJ027-IgG-A_S2_L001.clns IgG
C2-SUBJ053-IgM_S11_L001.clns IgM
