[MUMmer-help] nucmer error

[Wymant, C. <c.w...@im...>]

Dear MUMmer help,

>From a clean install of MUMmer, running
$ nucmer --maxmatch test1.fa test2.fa
gives the output
1: PREPARING DATA
sh: 1: Syntax error: "(" unexpected
ERROR: prenuc returned non-zero
regardless of what is in the fasta files; for example just
>MySequence
ACTG
still gives the error. Changing the --maxmatch option does not help. Please advise.

Thanks,
Chris Wymant
