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

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.
