Good morning , I want to ask you if we can say that cellranger and STARsolo generated to same output in my case. Thank you

cellranger count:

cellranger uses STAR to align the data: https://kb.10xgenomics.com/hc/en-us/articles/115003126432-What-version-of-STAR-is-used-in-Cell-Ranger-

You will want to run STARsolo with parameters recommended by author in this thread: https://github.com/alexdobin/STAR/issues/1381
