|
|
|
72 The RSeQC package provides a number of useful modules that can comprehensively evaluate high throughput sequence data especially RNA-seq data. “Basic modules” quickly inspect sequence quality, nucleotide composition bias, PCR bias and GC bias, while “RNA-seq specific modules” investigate sequencing saturation status of both splicing junction detection and expression estimation, mapped reads clipping profile, mapped reads distribution, coverage uniformity over gene body, reproducibility, strand specificity and splice junction annotation.
|
|
|
73
|
|

74 The RSeQC package is licensed under the GNU GPL v3 license.

|
93
|
|
|
94 Only use exonic reads
|
|
|
95 Renders program only used exonic (UTR exons and CDS exons) reads, otherwise use all reads.

107 - All transcripts were sorted in ascending order according to expression level (RPKM). Then they are divided into 4 groups:
|
|
|
108 1. Q1 (0-25%): Transcripts with expression level ranked below 25 percentile.
|
|
|
109 2. Q2 (25-50%): Transcripts with expression level ranked between 25 percentile and 50 percentile.
|
|
|
110 3. Q3 (50-75%): Transcripts with expression level ranked between 50 percentile and 75 percentile.
|
|
|
111 4. Q4 (75-100%): Transcripts with expression level ranked above 75 percentile.
|
|
|
112 - BAM/SAM file containing more than 100 million alignments will make module very slow.
