[MUMmer-help] Nucmer error

[Maia M. <mm...@yo...>]

Hi there,

I'm trying to run nucmer and compare a reference genome with a genome I
assembled using this code:

nucmer --maxmatch -l 100 -c 500 reference.fasta asm.fa

I am running MUMmer 4.0.0beta2 and I am getting the following error:

terminate called after throwing an instance of 'std::runtime_error'
  what():  First character must be a '>', got ''
Aborted

I have looked this error up and nothing seems to come up in relation to
mummer, do you have any idea what might be causing this? I'd appreciate any
suggestions.


Many thanks,
Maia Munteanu
