.. class:: infomark

**Purpose**

rnaQUAST is a tool for evaluating RNA-Seq assemblies using reference genome and gene database. In addition, rnaQUAST is also capable 
of estimating gene database coverage by raw reads and de novo quality assessment.

.. class:: infomark

**rnaQUAST pipeline**

To evaluate quality of the assembled transcripts, rnaQUAST takes a reference genome in FASTA format and optionally its gene database in 
GFF/GTF format. A user can provide either a FASTA file with transcripts, which will be aligned to the given reference genome using GMAP 
or BLAT. The alignments are analyzed to calculate simple metrics and then are matched against the isoforms from the gene database in order 
to obtain statistics that represent completeness and correctness levels of the assembly. In addition, rnaQUAST is capable of estimating 
gene database coverage by raw reads using STAR or TopHat2. For de novo quality assessment when reference genome and gene database are 
unavailable, the transcripts are analyzed using BUSCO.

.. class:: infomark

**Metrics and alignment analysis**

rnaQUAST calculates various metrics without using alignment information, e.g. length distribution and N50 of the assembled transcripts. 
Additionally, rnaQUAST computes the following statistics for the gene database: the total number of genes and isoforms, isoform and exon 
length distribution, average number of exons per gene, etc.

To analyze transcripts' alignments, rnaQUAST firstly filters out short partial alignments (shorter than a user-defined threshold, default 
value is 50 bp). Such short alignments are typically caused by genomic repeats and thus are ignored. Afterwards, rnaQUAST selects the 
best-scored spliced alignment for each transcript. If a transcript has more than one alignment with the highest score, it is reported 
as multiply aligned. Otherwise, it is considered to be uniquely aligned. If the best-scored alignment is discordant (e.g. the transcript 
has partial alignments that are either mapped to different strands or to different chromosomes) the transcript is classified as misassembled. 
Transcripts without misassemblies are analyzed to calculate such metrics as average transcript alignment fraction and mismatch rate.

For the simplicity of explanation, transcript is further referred to as a sequence generated by the assembler and isoform denotes a sequence 
from the gene database. rnaQUAST matches best-scored alignments of non-misassembled transcripts to the isoforms' coordinates and analyzes 
them to estimate how well the isoforms are covered by the assembly. rnaQUAST computes such metrics as database coverage (the total number 
of covered bases of all isoforms divided by the total length of all isoforms) and the number of 50%/95%-assembled isoforms. An isoform is 
considered to be x%-assembled if it has at least x% covered by a single transcript. Vice versa, to evaluate how well the assembled 
transcripts are covered by the isoforms, rnaQUAST estimates the number of unannotated transcripts (that align to the genome, but do not 
match to any isoform) and the number of 50%/95%-matched transcripts (that have corresponding fraction mapped to an isoform). Indeed, the 
thresholds described above (50% and 95%) can be varied by the user.
