  • -A takes a file with chromosome name aliases, which you're not providing and likely don't need.
  • -s takes a number indicating what sort of strand specificity you want. You likely want -s 2.
  • If you want to use these in edgeR/DESeq2/etc., don't use -O.
    • You probably don't want -f.

In general, run commands first and spot-check the results to see if anything went wrong. Also, start using new commands/tools by using the defaults.
