I am trying to analyze mouse RNA-seq expression data but am getting the following error during cuffmerge:

8:119910359-124345724 Warning: Skipping large bundle

I'm using Ensemble m38.69 (Accession #GCA_000001635.2). It seems that there is a giant gene annotated in that interval, GM20388. I understand that the default bundle size in cufflinks (I'm using v2.0.2) is 3,500,000 so I tried increasing the bundle size using the following command:

--max-bundle-length 8000000

Even with the bundle length increased to 8,000,000 I am still getting the same "Skipping large bundle" error. The entire cufflinks command is shown here:

cufflinks --max-bundle-length 8000000 -u -b Mus_musculus.GRCm38.69.dna.toplevel.fa -p 11 -o cufflinks_out/Sample10831 tophat_out/Sample10831/accepted_hits.bam

Any thoughts as to why I'm still getting the error?

Thanks!!

may be increase more, also check this post

Tried increasing to a bundle size of 100,000,000 and then 10,000,000,000. Neither one worked.

did you determine how to fix this error? I got the exact same problem in this genome coordinate.

Nope, haven't figured it out. Increasing the bundle size didn't seem to work.

As Sukhdeep says keep increasing it to even larger values.
