Detailed reports

The counts below do not include pseudogenes.

BUSCO analysis of gene annotation

BUSCO v4.1.4 was run in "protein" mode on the annotated gene set picking one longest protein per gene, and run using the metazoa_odb10 lineage dataset. Results are reported for the gene set from the primary assembly unit, and presented in BUSCO notation.

Alignment of the annotated proteins to a set of high-quality proteins

The final set of annotated proteins was searched with BLASTP against the UniProtKB/Swiss-Prot curated proteins, using the annotated proteins as the query and the high-quality proteins as the target. Out of 24732 coding genes, 17675 genes had a protein with an alignment covering 50% or more of the query and 3775 had an alignment covering 95% or more of the query.

Definition of query and target coverage. The query coverage is the percentage of the annotated protein length that is included in the alignment. The target coverage is the percentage of the target length that is included in the alignment.

Below is a cumulative graph displaying the number of genes with alignments above a given query or target coverage threshold. For comparison, corresponding statistics for other organisms annotated by the NCBI eukaryotic annotation pipeline were added to the graph.

Query: annotated proteins
Target: UniProtKB/Swiss-Prot curated proteins

Masking of genomic sequence

Transcript and protein alignments are performed on the repeat-masked genome. Below are the percentages of genomic sequence masked by WindowMasker and RepeatMasker (if calculated), for each assembly. RepeatMasker results are only calculated for organisms with complete Dfam HMM model collections.

For this annotation run, transcripts and proteins were aligned to the genome masked with WindowMasker only.

Transcript and protein alignments

The annotation pipeline relies heavily on alignments of experimental evidence for gene prediction. Below are the sets of transcripts and proteins that were retrieved from Entrez Nucleotide, Entrez Protein, and SRA, and aligned to the genome.

Transcript alignments

The alignments of the following transcripts with Splign were used for gene prediction:

RNA-Seq alignments

The alignments of the following RNA-Seq reads with STAR were also used for gene prediction:

  Hide alignments statistics, by sample (SAME, SAMN, SAMD, DRS)
  Show alignments statistics, by run (ERR, SRR, DRR)

Protein alignments

The alignments of the following proteins with ProSplign were used for gene prediction:
