error: "Only a column name can be used for the key in a dtype mappings argument"

[emaxortiz]

Hi Muhammed,
I'm trying to test lapa with RNAseq short reads. I'm using hisat2 for the mapping ( I built the hg38 with transcript index using the files suggested in the lapa tutorial). And my python version is 3.9

After fixing the gtf file and gave it the right format to all the inputs. Lapa failed after trying to process the bam for the first sample with the following error:

$ lapa --alignment samples.csv --fasta genome.fa --annotation genome_utr.gtf --chrom_sizes chrom_sizes --output_dir lapa_test

KeyError: 'Only a column name can be used for the key in a dtype mappings argument.'

I know this error is generated when the names in the columns don't match exactly, but I'm not so sure how to fix it.
Any suggestion is welcome.

Thanks.
