- buttons for expanding overlapped alignments are added to detailed assembly tracks
on Contig Alignment Viewers;
- additional colors (available in all viewers) for:
* ambiguous contigs,
* alternative blocks of misassembled contigs,
* misassembled contigs with >50% unaligned bases (see item 7 below).
- better performance on low resolution screens.
2. Python3 is now supported (versions 3.3, 3.4 and 3.5).
3. Several new options are added:
- "--scaffold-gap-max-size" for controlling maximum allowed size of scaffold gap
inconsistency in the corresponding type of misassembly (--scaffolds only);
- "--fragmented-max-indent" for controlling maximum allowed indent on each side
of the reference fragments to consider translocation as fake one (see manual for
details);
- "--blast-db" for specifying custom BLAST database instead of SILVA 16S rRNA for
searching probable references in MetaQUAST "without references" mode;
- "--space-efficient" for removing or even not creating space consuming auxiliary
files; all reports and plots (except Icarus viewers) are generated as usual;
- "--significant-part-size" renamed to "--unaligned-part-size", see details below
(see item 6 below).
4. New metric, report and plot are added (MetaQUAST only, combined reference only):
- possible misassemblies (number of putative interspecies translocations
in possibly misassembled contigs if each large unaligned fragment is supposed
to be a fragment of unknown reference);
- report of interspecies translocations number per each reference, saved to
interspecies_translocations_by_refs_<assembly_name>.info under
<output_dir>/combined_reference/contigs_reports/;
- plot of all found and supposed (possible) interspecies translocations, saved to
intergenomic_misassemblies.pdf under the same folder as above report.
5. New detailed report is added:
- all fully and partially unaligned contigs, their length, and unaligned parts are
listed in <output_dir>/contigs_reports/contigs_report_<assembly_name>.unaligned.info
6. Partially unaligned contigs are redefined in simpler and more logical way. Now
all contigs having at least one unaligned fragment of length greater or equal to
unaligned_part_threshold are considered as partially unaligned. The threshold is
controlled by --unaligned-part-size option (default value is 500 bp).
7. New processing of misassembled contigs which are mostly unaligned (> 50%):
- " half-unaligned with misassembly" metric is renamed to " unaligned mis. contigs"
and moved from detailed unaligned_report to detailed misassemblies_report
(stored under <output_dir>/contigs_reports/);
- " unaligned mis. contigs" metric is added to all main reports (TXT, HTML, PDF).
8. BED format is accepted for genes/operons annotations.
9. Minor changes in HTML reports:
- heatmap coloring is removed for metrics where best/worst values are undefined
(GC %, similar blocks, contigs, etc);
- split versions of scaffold assemblies are plotted with dashed lines (--scaffolds
option only).
10. Fixed issue of crashing E-MEM on OS X without gcc installed. Also, if E-MEM is
already installed on the system, it will be used instead of embedded E-MEM.
11. User-provided SAM/BAM files are now checked for correct chromosome names and
automatically corrected if needed and correction is possible.
12. Fixed incorrect behaviour of MetaQUAST on compressed assemblies in "without
references" mode.
13. Best set selection is improved (misassembly detection algorithm in case of multiple
ambiguous mappings of contig fragments). Now BSS takes internal overlaps into
account, so alignments with a short gap (in contig) are preferred over alignments
having large internal overlap if all other things are equal.
14. Fixed several minor bugs.
15. Icarus citation is updated.
16. Useful tips on running QUAST on large genome assemblies are added to FAQ section
of the manual (see Q14).
