====== Ixodes scapularis (Deer Tick) EvidentialGene gene construction set ========
2014-jun-07, by Don Gilbert, gilbertd at indiana edu
http://arthropods.eugenes.org/EvidentialGene/arthropods/deertick/

This is a 'reference-free' gene set assembly from mRNA-seq, without reference made to
a genome assembly nor training/mapping from other species genes. As such it has different 
values than genome-based gene sets, one important one is no external artifacts or errors 
contribute to these genes.  Any protein orthology measured has not been influenced by 
gene modelling using other species (with their artifacts), and genome assembly errors.

Ixodes scapularis mRNA-seq is of NCBI SRA public data BioProject PRJNA239331,
accessions listed in itick_pj239331_nobact.csv

  60000 short half of noho, <= 110 aa, 24000 are partial or/and utrpoor/bad.  discard all?
  check random set of noho for NR blastp hits .. any contams, TE genes? bacteria?
  likely that large NR protein set will categorize many of these in 3 bins:
  dont know w/o doing blastp what proportion of noho set to keep
   1. eukaryote (may include ixodes/ticks)
   2. bacterial/contam
   3. transposon/virus/contam
   4. no detectable homology .. probable ixodes, maybe not
