Hi there,

I am trying to run the dexseq_prepare_annotation.py script and the code keeps failing after parsing the first line of the gtf. Specifically, the code is failing at the first step where exons and their respective gene and transcript IDs are placed into a GenomicArrayOfSets. I've tried this with three different GTFs from Ensembl and all three lead to the same error.

Traceback (most recent call last): File "/Library/Frameworks/R.framework/Versions/4.0/Resources/library/DEXSeq/python_scripts/dexseq_prepare_annotation.py", line 56, in <module> exons[f.iv] += ( f.attr['gene_id'], f.attr['transcript_id'] ) File "src/HTSeq/_HTSeq.pyx", line 451, in HTSeq._HTSeq.ChromVector.__iadd__ File "src/HTSeq/_HTSeq.pyx", line 464, in HTSeq._HTSeq.ChromVector.apply File "...miniconda3/lib/python3.9/site-packages/HTSeq/_HTSeq_internal.py", line 33, in ChromVector_steps for start, stop, value in cv.array[cv.iv.start:cv.iv.end].get_steps(): File "...miniconda3/lib/python3.9/site-packages/HTSeq/StepVector.py", line 410, in get_steps prevval = startvals.next().second AttributeError: '_StepVector_Iterator_obj' object has no attribute 'next'

Python version = 3.9.5 Htseq version = 0.13.5 DEXSeq version = DEXSeq_1.36.0

Apologies for late reply. Could you share the link to the gtf source?
