sdriscoll,

Note that in the case of a provided annotation, eXpress and Cufflinks use the same information to determine the transcript abundances. The spliced reads are no longer spliced in the...

There is a new utility included with cufflinks now, called "gffread", which should be able to extract spliced transcript sequences from a GFF/GTF. This is now documented on this page (scroll down to...

This type of bias (as well as sequence-specific bias) is corrected for in Cufflinks. The importance of doing this correction is detailed in our paper here: http://genomebiology.com/2011/12/3/R22/

This error is output by samtools (which Cufflinks calls) if you are using a SAM instead of a BAM. However, Cufflinks recognizes this and switches to SAM support, so there is no issue.

Yes, but it will probably be somewhat involved. You will need to build your GTF so that isoforms correctly overlap in the genome coordinates. You will then need to adjust your SAM alignments so...
