Hi I had the previously posted problem as well that I have the error message from Psi-blast
sh: line 1: 33440 Segmentation fault (core dumped) /usr/users/metbio/chua/ITASSER/I-TASSER2.1/blast/bin/blastpgp -b 1000 -j 3 -h 0.001 -d /usr/users/metbio/chua/ITASSER/I-TASSER2.1/nr/nr -i protein.fasta -C psitmp.chk -Q pssm.txt > blast.out
I have checked that the pssm.txt is not empty
I am running it in a cluster in parallel run style, which blast package from NCBI I should install?
