I installed MPI-BLAST in linux (ubuntu 16.04) , but while running query its generates an error, which may be pointed towards DATABASE.

to create database i ran this query:

$mpiformatdb -N 16 -i /home/ntm/Downloads/MPI_BLAST_MTB_ASM/all_ASM.fna -o /home/ntm/mpiblast/mtb_ASM

result was:

Reading input file

111Done, read 86563441 lines

Database type unspecified, assuming nucleotide

Breaking all_ASM.fna into 16 fragments

Executing: formatdb -i /home/ntm/Downloads/MPI_BLAST_MTB_ASM/all_ASM.fna -p F -N 16 -o T 

Created 16 fragments.

<<< Please make sure the formatted database fragments are placed in /home/ntm/mpiblast/ before executing mpiblast. >>>

i ran this query:

$mpiexec -n 18 mpiblast -p blastn -d mpiblast/all.fna -i /home/ntm/samples/test_data/100/100.fasta -o /home/ntm/samples/test_data/100/r_100.txt

and get this error:

Error opening /home/ntm/mpiblast/mpiblast/all.fna.mbf

open: No such file or directory

Fatal Error:

Unable to access fragment list file

MPI_ABORT was invoked on rank 17 in communicator MPI_COMM_WORLD 
with errorcode -1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.

You may or may not see output from other processes, depending on

exactly when Open MPI kills them.
