Question: Why MeGAMerge terminated with minimus.fasta 1>/dev/null 2>/dev/null failed: error

I am trying to merge contigs, generated from different assemblies with MeGAMerge, but it failed after running few hour !! Following are the error I got on command prompt. Any suggestions??

perl MeGAMerge-1.1.pl -f MergedDIR allContigs_MIRA_assembled.fa
Running Newbler assembly with 308261 sequences
runAssembly -force -large -rip -mi 98 -ml 80 -pairt -cpu 4 -a 200 -o MergedDIR/newbler MergedDIR/newblerIn.fasta 1>/dev/null 2>/dev/null
Running Minimus2 with 331388 sequences
minimus2 -D CONSERR=0.06 -D MINID=98 -D OVERLAP=80 MergedDIR/minimus.fasta 1>/dev/null 2>/dev/null
minimus2 -D CONSERR=0.06 -D MINID=98 -D OVERLAP=80 MergedDIR/minimus.fasta 1>/dev/null 2>/dev/null failed:

Well, you might need to check the MeGAMerge log file for detail error message. Can you please reply with your error message from log file please?

Thanks Jit, here is the tail section/error section of the log file

Thanks for the update Neelam.

This is specific problem of Mummer,

/usr/bin/mummer: suffix tree construction failed: textlen=1584056222 larger than maximal textlen=536870908
ERROR: mummer and/or mgaps returned non-zero

so you might need to re-install mummer3 http://mummer.sourceforge.net/ with following command:

> make clean
> make CPPFLAGS="-O3 -DSIXTYFOURBITS"

And then set the path in MeGAMerge script and re-run it.

Cheers

I got this new error, and just wondering why ???

You might need to update the path of following in minimus2 script

NUCMER=/home/Tools/MUMmer3.23/nucmer
DELTAFILTER=/home/Tools/MUMmer3.23/delta-filter
SHOWCOORDS=/home/Tools/MUMmer3.23/show-coords

with re-installed mummer3 path. By default, it look into bin directory.
