## analysis

 

### genomic context

 

The broader arthropod/chelicerate context for the _P. litorale_ genome assembly.

 

- araneae.tsv: repeat makeup of published chelicerate assemblies

- arthropoda.tsv: genome assembly statistics for arthropod genomes. From NCBI Genomes.

- modern_taxids.txt: list of taxonomic IDs for species; made to be submitted to NCBI Taxonomy.

- tax_report.txt: the full taxonomic report for each query species. Contains tax IDs for the entire lineage.

- total_repeats.tsv: total repeat content of published chelicerate genomes.

 

### Homeobox genes

 

Files concerning the Homeobox gene cluster analysis. Each folder (hro, irx, nkx, sine) contains the

candidate sequences from Aase-Remedios et al., the P. litorale sequences that matched, the multiple

sequence alignment, the trimmed alignment, and the tree files.

 

Additionally, the hox/ folder contains the analysis done for the AbdA gene, with searches performed

against the de-novo assembled transcriptomes (.m8 files).

 

Finally, the r2_g3735/ folder contains the analysis of the r2_3735 gene model, which is found in the

Hox cluster area on the P. litorale genome. Sequence searches against NCBI nr and the developmental

transcriptomes show that the gene has putative homologs in other taxa and is expressed throughout

development.
