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 for each assembly. RepeatMasker results are only used for organisms for which a comprehensive repeat library is available.
For this annotation run, transcripts and proteins were aligned to the genome masked with WindowMasker only.| Assembly name | Assembly accession | % Masked with RepeatMasker | % Masked with WindowMasker |
|---|---|---|---|
| ASM70822v1 | GCF_000708225.1 | 4.41% | 18.22% |
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, aligned to the genome by Splign or ProSplign and passed to Gnomon, NCBI's gene prediction software.
Depending on the other evidence available, long 454 reads (with average length above 250 nt) may be aligned as traditional evidence and reported in the Transcript alignments section or aligned with short reads and reported in the Short read transcript alignments section.
