I have assembled raw short RNA-seq reads into Transcripts using Trinity. My raw reads were strand-specific. What should I set "--strand" in Diamond?

I used Trinity to de-novo assemble my RNA seq raw reads. These reads were generated using a strand-specific method. Now I want to do a BLASTx using Diamond. I am unsure what I should keep under its ...

Discrepancy with featurecounts analysis using a forward stranded and reverse stranded protocol

My RNAseq analysis pipeline is as follows: fastqc (read quality is good, some overrepresentation of adaptor sequence) → trimmomatic (trimmed adaptor sequence, qc report after trimming suggests the ...

Why is there antisense sequence in RNAseq data

I'm looking at RNAseq data from CCLE. The data is paired-end. Take the cell line Hs578T and the gene HRAS as an example. The cell line carries a G12D mutation (c.35G>A), so the change in cds is: <...

Run cuffcompare in strand-agnostic mode

Is there a way to run Cufflinks' cuffcompare in a strand-agnostic mode? I would like to do this because I have some RNA-seq datasets derived from an unstranded run, that should be compared to a ...

At what processing step should library strandedness type be taken into account?

Suppose I have single-end RNA-seq data for which the reads in the fastq file are reversed with respect to the original extracted RNAs. Suppose I have the following workflow: Map the reads on the ...
