WebThe number of unique mapping reads crossing the junction. The number of multi-mapping reads crossing the junction. Maximum spliced alignment overhang. The unmapped files contain the unmapped reads and partially mapped reads (i.e. mapped only one mate of a paired-end read). These reads are stored following the FASTQ specification. WebJan 12, 2024 · I'd like to count the number of reads in the forward files and print the output to a file with the read count and file name.
