Here we present an alternative approach, where we consider all possible mappings for each read, and assign each read to a location based not only on that read, but also based on all of the other reads generated from the dataset.
Therefore jMHC sorted out the reads and assigned them to the individuals, and then removed the sequences lacking complete primers or tags, and sequences that had ambiguous base pairs (Ns).
For each of these pairwise comparisons we performed a Fisher's Exact Test on counts of mapped reads and assigned statistical significance using a Bonferroni-corrected p-value (p < 3.9 × 10-6; see Materials and Methods).
In that report, the authors have leveraged the ability of a next-generation sequencing to count individual sequencing reads and assign them to either known or 'dark matter' RNA categories.
Data from the PGM runs were processed on the Ion Torrent server using a platform-specific pipeline incorporated in Torrent Suite v4.2.1 (Life Technologies) to obtain sequence reads, trim adapter sequences, filter and remove poor signal reads, and assign the reads to a given barcode.
At the beginning, all primers are considered to be equally probable matches for the given read and hence assigned a probability of pprimer = 1.
Students should take notes as they read and discuss their assigned section.
First the transcripts were read and initial codes assigned.
For the first stage of analysis, the transcripts were read and the text assigned initial codes by two of three independent researchers (HB, AR, CS).
