WebNov 13, 2013 · featureCounts performs precise read assignment by comparing mapping location of every base in the read or fragment with the genomic region spanned by each feature. It takes account of any gaps (insertions, deletions, exon–exon junctions or fusions) that are found in the read. WebIt appears you use Mercury Network to manage orders as a client. However, you are attempting to log onto the vendors area. The Vendor site is used by vendors such as …
WebIf you did in fact align to the genome, do note that the in-built annotation is based on NCBI Gene IDs, and GenCode is based on EBI/EMBL, so the chromosome in the first instance will be e.g., chr1, whereas in the second it will be just 1. You will probably either need to generate an SAF file, or get a GFF or GTF file from GenCode. WebJun 20, 2024 · At this point fastqc looks good across the board, so on to alignment.

This option must be used together with '-M' or '-O' or both. When '-M' is specified, each reported alignment from a multi-mapping read (identified via 'NH' tag) will carry a fractional count of 1/x, instead of 1 (one), where x is the total number of alignments reported for the same read. new ways for families course
