Exception : [rapidjson internal assertion failure: IsObject()]

Question

[Andrea]

I've installed Salmon and made the index, but once I run the analysis, I've got this error:

(salmon) andrea@Precision-7920-Tower:/hdd_a/andrea/Salmon$ sudo salmon quant -i GRCh38_salmon_index/ -l A -r /hdd_a/andrea/Salmon/Fastq/1_vehicle_R1.fastq.gz --validateMappings -o /Output/

sudo salmon

you should never run such tool as sudo
