Notable changes to minimap2:
-
New feature: added the
splice:sr
preset for short RNA-seq read alignment.
Users may use-j
to specify known gene annotation to improve spliced
alignment close to the ends of short reads. Also added--write-junc
and
--pass1
for 2-pass short-read RNA-seq alignment. -
Experimental feature: read splice scores from a file specified by
--spsc
and consider the scores during base alignment. The feature makes it possible
to apply advanced splice models and to improve spliced alignment. -
Change: adjusted the mapping quality calculation for spliced alignment.
-
Bugfixes: a) missing overlap alignment when base alignment is requested
(#969); b) incorrect summary information for long genomes (#1192); c)
missing parameter check for--score-N
(#1226). -
Improvement: a) warn about absent junction files (#1229); b) report an error
if a wrong preset prefixed with "splice" is specified (#589).
Notable changes to mappy:
Minimap2 now supports short/long genomic/RNA-seq read alignment along with
contig alignment and all-vs-all read overlapping. It produces identical genomic
long-read or contig alignment to v2.27. Short genomic read alignment and the
mapping quality of long RNA-seq read alignment may slightly differ in very rare
cases.
