Comment: C: short RNA reads alignment
... I mapped my reads against Human genome (Homo_sapiens.GRCh38.dna.primary_assembly.fa). Did you mean my reads are contaminated by rRNA sequences ? ...

Comment: C: short RNA reads alignment
... Hi genomax, Thank you for your suggestion, I've used BBMap with the values of parameters as you suggested, and I got the following results (I used another sample different from the one used for STAR alignment, but both of them are generated using the same protocol): ------------------ Res ...

Comment: C: All my reads fall in intergenic regions ?
... Since the length of my reads is distributed between 22-50 nt, I think it is clear I got a high rate of multiple mapped reads. A very short read of 25 nt will get a higher number of multiple aligned locations on the genome than a read of a higher length. I am right ? ...

Comment: C: All my reads fall in intergenic regions ?
... It is total RNAseq experiment. The sequencing has been done on degraded RNA samples (single-end) and with a particular library preparation protocol, that is why I got very short RNAseq reads. We don't target any class of RNAs. ...

All my reads fall in intergenic regions ?
... Hi biostars, I've performed an alignment using Bowtie on small RNAseq reads (22-50 nt) from total RNA-Seq sequencing experiment. I got almost 90% of multiple mapped reads. Then, I counted the reads per biotype (gtf file from Ensembl) using mmquant program (which is designed for counting tasks in th ...

Answer: A: How to calculate distribution of mapped read over classes of RNA?
... If you get a high rate of multiple mapped reads and a low rate of uniquely mapped reads then the process to find the percentage of mapped reads by biotype will be slightly difficult. A classical way to do that is to perform the mapping and then counting the number of reads per features (featureCount ...

Questions about STAR and Bowtie (not Bowtie2) mapping
... Hi all, I want to perform an alignment of short reads against a reference genome (human genome from Ensembl). For that I've used STAR, and Bowtie (not Bowtie2). I've some questions about that. 1- I've used STAR by setting the more important parameters as follows: --outFilterScoreMinOverLread ...
