I think I fixed it. The adapter for my files should be TGGAATTCTCGGGTGCCAAGG. From what-sequences-do-i-use-for-adapter-trimming under the category of TruSeq Small RNA.
Now I get ~60% mapping. I am not sure if this is sufficient, though.

miRDeep2 and adapter trimming
I am trying to align a miRNA-seq FASTQ file using the mapper.pl from miRDeep2 but I am not having any luck.
The reads in the FASTQ file are ~50bp.
I am not sure where my mistake is as I get 46380 reads mapped (less than 1.6% of total reads). This is my code
Code:mapper.pl /mnt/d/work/NNNN_1_SAMPLE1_ATCACGA_S2_L001_R1_001.fastq -e -h -j -k ATCACGA -l 16 -m -p GRCh38_primary_assembly_genome -s /mnt/d/work/tools/mirdeep2/test/2.collapsed_reads.fa - t /mnt/d/work/tools/mirdeep2/test/2.grch38.arf -n -v
I am not sure how to proceed. Any help would be appreciated.Last edited by Anastaziel; 10-04-2019, 11:11 AM.Tags: None

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
