If I try running BLASTALL with my transcriptome data as the database, I get this error:

[blastall 2.2.22] ERROR: SeqPortNew: lcl

All the names of the sequences are too similar so I have to rename them--I am just going to rename them by number.
awk '/^>/{print ">" ++i; next}{print}' < DR_091_Mobl_MOE_assembled.fasta > renamed_DR_091_Mobl_MOE_assembled.fasta

#export the path the blast
export PATH=$PATH:/Users/laurelyohe/blast-2.2.22/bin/

#format the database 

#because the transcriptome is bigger than the indices, it will serve as the database

formatdb -i renamed_DR_091_Mobl_MOE_assembled.fasta -o T -p F

#run blast

blastall -p tblastx -d renamed_DR_013_Mored_MOE_assembled.fasta -i OR_VR_indices.fasta -e 1e-06 -v 5 -b 5 -a 2 -o ./DR_013_Mored_MOE_assembled_v_OR_VR_indices.tblastx

#now we need to parse the BLAST script

perl ~/Scripts/parse_bls.pl --i DR_091_Mobl_MOE_assembled_v_OR_VR_indices.tblastx > DR_091_Mobl_MOE_assembled_v_OR_VR_indices.tblastx.parsed

#next combine the parsed file with the sequences

Here is a blog that gives excellent Trinity instructions:

#for paired end reads, combine each side of pairs into one file

cat pair.DR004_Artibeus_Jamaicensis_MOE_ACAGTG_L001_R1* >> Arjam_MOE_R1.fq

cat pair.DR004_Artibeus_Jamaicensis_MOE_ACAGTG_L001_R2* >> Arjam_MOE_R2.fq

#run a trimming script

python ~/Scripts/q-trim.py Arjam_MOE_R1.fq Arjam_MOE_R1_trim.fq

#woops I run into this error:

importerror no module named screed

#it looks like I need the "screed" module for this; looks like I also need to update "setup tools"

#first install pip

sudo python get-pip.py

pip install ipython #not sure what this did

#still missing the screed module

sudo pip install setuptools --upgrade

sudo pip install git+https://github.com/ged-lab/screed.git

#okay seems to be working now

#trimmed with the default setting in which a minimum Qscore = 5

#minimum length = 30; lets see how this works

python ~/Scripts/q-trim.py Arjam_MOE_R1.fq Arjam_MOE_R1_trim.fq

python ~/Scripts/q-trim.py Arjam_MOE_R2.fq Arjam_MOE_R2_trim.fq

#now i need to assemble paired reads--extracting only the pairs using both.py

python ~/Scripts/both.py Arjam_MOE_R1_trim.fq Arjam_MOE_R2_trim.fq

#this creates two files ...R1_trim.fq.both and R2_trim.fq.both

#this script took about one hour to run

#finally time to run trinity!

Trinity.pl --seqType fq --left Arjam_MOE_R1_trim.fq.both --right Arjam_MOE_R2_trim.fq.both --CPU 4 --JM 20G --output trinity_output/

Everything is up and running now. Stay tuned.
