Aligned option using star #21

Closed nttg8100 closed 1 month ago

nttg8100 commented 1 month ago

In ran on the star 2.7.1a star aligner. The option --chimOutType is not set correctly when I ran it showed me the conflict options. https://github.com/ylab-hi/ScanNeo2/blob/main/workflow/rules/align.smk#L33C1-L33C34

EXITING because of fatal PARAMETERS error: --chimMultimapNmax > 0 (new chimeric detection) presently only works with --chimOutType Junctions
SOLUTION: re-run with --chimOutType Junctions

However, the pipeline already sets with --chimOutType WithinBAM HardClip. Currently, I replace the option as recommended automatically by the software. Can you check on the current smk align rule. If it is not set correctly, please update the pipeline.

Hello,

is there a reason you are using 2.7.1a and not 2.7.10b (which is the one used by the snakemake star wrapper - should probably update to 2.7.11b)? Or are you not able to use conda? As the authors of STAR are mentioning here: https://github.com/alexdobin/STAR/issues/1288 It's possible to call --chimMultimapNmax with --chimOutType WithinBAM in recent versions. We need to have it within the BAM (mainly because of Arriba) and would lose information otherwise.

I see. Thank you for your clarification. I thought it could be the STAR version issue so I provided above. Currently, I have been used the image from STAR 2.7.1a for calling gene expression, fusion and this alt splicing, exonic introns. I will update later for my pipeline to use a unique version of STAR. Thank you for your support.
