junction_saturation.py¶
Assess whether sequencing depth is sufficient for junction discovery. As sequencing depth approaches saturation, fewer new junctions are discovered.
Usage¶
Options¶
| Option | Description | Default |
|---|---|---|
-i, --input-file | Alignment file in BAM or SAM format | Required |
-o, --out-prefix | Prefix of output files | Required |
-r, --refgene | Reference gene model in BED format | Required |
-l, --percentile-floor | Sampling starts from this percentile | 5 |
-u, --percentile-ceiling | Sampling ends at this percentile | 100 |
-s, --percentile-step | Sampling step size | 5 |
-m, --min-intron | Minimum intron size (bp) | 50 |
-v, --min-coverage | Minimum supporting reads to call a junction | 1 |
-q, --mapq | Minimum mapping quality for "uniquely mapped" | 30 |
Output¶
prefix.junctionSaturation_plot.r— R script for saturation plotprefix.junctionSaturation_plot.pdf— saturation curve (known, novel, all junctions)
