@gringene @nanopore Yes, absolutely. I am using Mus_musculus.GRCm39.dna.primary_assembly.fa as a reference, from ftp.ensembl.org/pub/release-10

Note that this is not limited to the region I showed in that post, you can essentially pick any gene and see a similar picture.

As an example, here is a zoom of one of the alignments I get... there is obviously something odd going on...

@nicolaromano @gringene @nanopore you typically see things like that when the reference in IGV does not match with the reference used for alignment - i.e. the coordinates don't match with the sequence

@wdecoster @gringene @nanopore That was my first thought as well, but I see the same when importing the reference I used in IGV. Also, I used the same reference to align directly on the MinION and that one looks fine... Good suggestion, though, I will double-check again tomorrow just in case I have selected the wrong file somewhere.
