Get -400bp to +50bp sequence of gene from gff3 file
... Dear all, I have used bedops and bedtools to obtain -2000bp upstream of my gene start (based on gff3 coordinates) file and the scaffold fasta file of the genome.While I know how to get upstream, I do; however want to get per say +50bp upstream of the gene start too. Is there a way of getting the re ...

Gene correlation analysis after deseq2
... I have 8 RNA libraries (4 reps per each of two conditions - tissue specific). I have approx 500 genes upregulated and 100 genes downregulated in the tissue of interest. I have a matrix of deseq2 normalised counts for all of the genes which I've pulled the differently expressed gene records from. ...

Multiple fasta file : calculate % composition of amino acids
... I've come across Expasy protein param... it's limited in the sense you can only copy/paste 1 sequence at a time. Is there an alternative approach via command line to calculate alphabet % composition of each >sequence? I haven never ventured into Biopython. I mostly use R and command line. All he ...

Refseq vs original genome assembly and issues
... A long winded post with multiple questions to gauge the consensus of the 'correct' approach to RNA-seq alignment when there is a Refseq vs published assembly version of a genome present. I've got the scenario where there is a published genome available as V1.0 and V1.1 (Genbank), and also on refseq ...

Comment: C: STAR two -pass mode - lower alignment rate than one pass mode?
... If anyone wants to know why... see below: > Some drop in the uniquely mapped reads in the 2nd pass is to be > expected, but it's typically ~1-2%. It's caused by the reads with > short splice ovehangs, which can be mapped to multiple junctions. ...

STAR two -pass mode - lower alignment rate than one pass mode?
... Hi guys, Quick question. I've performed a two-step alignment with STAR 2.6a. It seems my unique alignment rates are approx 1% (85%) lower when performing two pass, than the original one pass mode (86%). I thought the aim of two-pass mode was to increase the number of reads mapping to novel splice j ...
