mirData: Example of IsomirDataSeq with human brain miRNA counts data
Description
This data set is the object return by IsomirDataSeqFromFiles
.
It contains miRNA count data from 6 samples: 3 newborns and 3 elderly
human individuals (Somel et al, 2010).
Use colData

Data is available from GEO dataset under accession number GSE18069.
Samples used are: GSM450597, GSM450598, GSM450600,
GSM450604, GSM450610 and GSM450609 . Every sample was analyzed with seqbuster tool, see
http://seqcluster.readthedocs.org/mirna_annotation.html for
more details. You can get same files running the small RNA-seq
pipeline from https://github.com/chapmanb/bcbio-nextgen. Adapter removal with the following parameters:
adrec fastq_file TCGTATGCCGTCTT 8 1 0.34
miRNAs annotation with the following parameters:
miraligner adrec_output mirbase_files hsa 1 3 3 out_prefix
The data was created with isomiRs-package
package: library(isomiRs)
