Dear arthropod scientists,

Publicly available RNA-Seq data from NCBI sequence archive are listed here
http://arthropods.eugenes.org/EvidentialGene/arthropods/rnasets_srapublic/

These are suitable for assembly to complete species gene sets.  Some of these
arthropod species lack existing public gene sets, or have fragmented low-quality genes.
These will be interesting and valuable to assemble into good quality gene sets, which
the EvidentialGene pipeline is now ready to do.  

Please see the subset lists, sra_rnaseq*.arpods,insects,flies.listan, 
arpods = arthropods not insects, insects = not diptera, flies = dipterans (Drosophila, etc.)

Find some of these species gene set assemblies in EvidentialGene/arthropods/
Ixodes scapularis (deer tick) is an assembly in progress.  A few more good gene sets
of non-insect arthropods will help flesh out the arthropod gene taxonomy.

Potential collaborators or biologists with interest in species in these RNA sets 
please contact me.  As I'm out of funds just now, anyone who can pay for expert
gene construction from mRNA has priority.

EvidentialGene: Gene-omes from mRNA-seq assembly overtake genome gene-predictions.
An existing dogma in genome projects, that quality of a gene set is dependent on the 
quality of the genome assembly, is no longer accurate.  mRNA-seq assembly now does as well 
or better than genome-gene modelling.
