Hello!, I'm having problems with Cuffdiff analysis of gene Diff. expression. The code is:

cuffdiff -o (dir_output) --library-type=fr-firststrand -b ./dir/dir/file.fa -L Mock,Treated -u ./dir/file_gene_models.gtf

and followed by the inputs (with replicates).

In the terminal, the following is printed:

*Warning: Could not connect to update server to verify current version. Please check at the Cufflinks website (http://cufflinks.cbcb.umd.edu).
[11:19:22] Loading reference annotation and sequence.
[11:19:23] Inspecting maps and determining fragment length distributions.
Segmentation fault: 11*

As a result, I get all expected files but with NO content (0 bytes).

Has anyone encountered such problem? I have a macbookpro with 8gb RAM and close to 140gb free space.

Thanks!

Low memory, reported here: cuffdiff error: Segmentation fault: 11

Suggestions are to start from e.g. 10GB on: Memory and Runtime Cufflinks

Do you really need cufflinks, there are newer tools both differential gene and transcript level analysis that need far lower memory.

You can use DEseq2 for the same as it is more updated method
