[MUMmer-help] mummer: suffix tree construction failed

[grid b. <gri...@gm...>]

Hi Collegues,

I tried use mummer for bacterial genomes alignment.
The command line is : ./mummer -maxmatch -b ref.fa query.fa > xaa.out
Their are 200 reference sequences and the total length is : 752255529
There was error information reported by mummer: "  ./mummer: suffix tree
construction failed: textlen=752255529 larger than maximal textlen=536870908
"
I want to know if there is limit for reference file size and sequences
number and also, I find mummer occupied huge memory (about 6GB) when I gave
one about 300MB reference file.
How should I do like this case? Do I have to split reference file to one
sequence one file to do alignment?
Any ideas?

thank you,
