QualiMap
Quality control of alignment data and its derivatives like feature counts
The module supports the Qualimap commands BamQC
and RNASeq
.
Note that Qualimap must be run with the -outdir
option as well as
-outformat HTML
(which is on by default). MultiQC uses files
found within the raw_data_qualimapReport
folder (as well as genome_results.txt
).
Qualimap adds lots of columns to the General Statistics table. To avoid making the table
too wide and bloated, some of these are hidden by default (Error Rate
, M Aligned
, M Total reads
).
You can override these defaults in your MultiQC config file - for example, to show
Error Rate
by default and hide Ins. size
by default, add the following:
table_columns_visible:
QualiMap:
general_error_rate: True
median_insert_size: False
See the relevant section of the documentation for more detail.
In addition to this, it's possible to customise which coverage thresholds calculated by the Qualimap BamQC module (default: 1, 5, 10, 30, 50) and which of these are hidden in the General Statistics tablewhen the report loads (default: all hidden except 30X).
To do this, add something like the following to your MultiQC config file:
qualimap_config:
general_stats_coverage:
- 10
- 20
- 40
- 200
- 30000
general_stats_coverage_hidden:
- 10
- 20
- 200
