Data processing Mature and hairpin microRNAs were downladed from mirbase.org 2013-06-22
Preprocessing with fastx, http://hannonlab.cshl.edu/fastx_toolkit/index.html
The adapter TGGAATTCTCGGGTGCCAAGGAACTCCAGTCAC was removed
Sequences shorter than 15 nt were removed.
A fasta file with read counts was produced for each sample
Bowtie2 was used for alignment. Reference : Langmead B, Trapnell C, Pop M, Salzberg SL. Ultrafast and memory-efficient alignment of short DNA sequences to the human genome. Genome Biol 10:R25.
Bowtie indices were built using the mature and hairpin files from mirbase.
Alignment was performed for the reads of each sample. Default bowtie2 scores were used
For each sample and micro-RNA, the total count was found. The counts were multiplicatively normalized such that each sample had the same total count. The counts were logarithm tansformed by adding a pseudocount of 1 to all counts and taking the base 2 logarithm.
Genome_build: Mirbase release 19
Supplementary_files_format_and_content: csv file with normalized counts for the microRNAs for each sample
