This value is specified with the --rna-mapq-unique option. … WebComma-separated list of files containing single-end reads or upstream reads for paired-end data. By default, these files are assumed to be in FASTQ format. If the --no-qualities option is specified, then FASTA format is expected. downstream_read_file(s) Comma-separated list of files containing downstream reads which are paired with the upstream ...

WebI have been using STAR for our RNA-Seq samples. The final.out log file reports percentage of uniquely mapped reads along with percentage of reads that map to multiple loci (less than or equal to 10) and percentage of reads mapping to too many loci (greater than 10). However, I want to break down the multiple loci part to individual counts: Reads mapping … WebThe cuffdiff function operates in two distinct steps: the function first estimates abundances from aligned reads, and then performs the statistical analysis.

WebApr 16, 2024 · 0.33 is still pretty low for the minimum score/mapped length - it means you are allowing alignments that are 1/3 of the total read length. Any value <0.5 will allow for single-end alignments (i.e. only one mate aligned).
