=Probe Design ([[Daniel:Notebook/HiResChrPaint/2014-6-16|Started 06/17/2014]])= [[Daniel:Notebook/HiResChrPaint|Back to Calendar]] ==Probe Mining== The OligoArray script might actually need the blast database broken up into 1kb chunks for some reason. So, let's try that. #Create BLAST database from fragmented genome ##formatdb -i in_hg38.fas -p T -o F [formatdb] WARNING: Cannot add sequence number 1953021 (lcl|range=hg38:1953020000-1953020999) because it has zero-length. [formatdb] FATAL ERROR: Fatal error when adding sequence to BLAST database. So that's a fatal error. The instructions call for concatenating all the fasta files into one. I did this step using cat, but they suggest using their java script, so I'll try that. #Concatenate fasta files ##java ConcatenateFiles hg38_cat.fas *.fa #Fragment genome into pieces ##python ../bin/input_blocks.py ##''Please enter the filename, "chr2R_sorted_oligo.txt" or "chr2R_intersect.bed" etc.:'' hg38_cat.fas ##''Please enter the chromosome or assembly, "chr1 or ch2R, etc.:'' hg38 Killed Couldn't have said it better myself. Trying again using the Wu lab (Oligopaints) version of the fasta file. This is an older version (hg19/gr37, not gr38), but it'll have to do. #Format BLAST database ##formatdb -i hg19.fas -p F -o T #Run OligoArray2 ##java -Xmx8192m -jar /home/djacobse/blastdb_hg38/OligoArray2_1/OligoArray2.jar -i in_caskgene.fas -d hg19.fas -o oligo_caskgene.txt -r rejected_oligo.fas -R caskgene.log -n 30 -l 60 -L 60 -D 1000 -t 55 -T 65 -s 70 -x 70 -p 35 -P 80 -m "CCCC;GGGG;TTTTT;AAAAA" -g 2 Start range=chrX:1157000-1157999 Running Blast (-e 0.0)... For sequence range=chrX:1157000-1157999, the following exception was caugth: java.io.IOException: Cannot run program "blastall": java.io.IOException: error=12, Cannot allocate memory New problem, sort of. Looks like it can run OligoArray for a little while (gets through about 5000 bp or so), then says it can't allocate memory. Not sure what that's all about. I may be allocating more memory than is available for allocation with this command, so I'll try again without the memory allocation flag. I may also need to try again using a different (smaller) memory allocation flag. #Run OligoArray2 ##java -jar /home/djacobse/blastdb_hg38/OligoArray2_1/OligoArray2.jar -i in_caskgene.fas -d hg19.fas -o oligo_caskgene.txt -r rejected_oligo.fas -R caskgene.log -n 30 -l 60 -L 60 -D 1000 -t 55 -T 65 -s 70 -x 70 -p 35 -P 80 -m "CCCC;GGGG;TTTTT;AAAAA" -g 2 [[Category:HRCP]] [[Category:Probe Mining]] [[Category:OligoArray]]
