Use --quantTranscriptomeBan Singleend to allow insertions, deletions ans soft-clips in the transcriptomic alignments, which can be used by some expression quanti?cation software (e. With the integration of matched RNA sequencing data, the translation efficiency (TE) of genes can be calcul. Gene counts were computed for each sample by STAR by setting quantMode as GeneCounts; STAR uses a similar algorithm to the htseq-count function from the HTSeq package and should produce identical counts as htseq-count run in default mode (i. Getting very low numbers of annotated reads from STAR/mm10 Hi all, I'm trying to analyze RNA-seq data (mouse, multiplexed Nextera XT libraries) using STAR and I'm having the problem that I'm getting mostly "no feature" and hardly any annotated reads downstream.

Again, we are using a wrapper script that simplifies the process of calling STAR for all samples. 1 ) to calculate read counts while taking into account only uniquely mapped reads (non‐default parameters: ‐r pos ‐m intersection‐nonempty ‐s reverse). This is primarily due to the low sequencing depth on the paired-end sequencing data. the exiting file path will be used as source for the workflow. Genes were quantified using either HTSeq v0.
