Error: Invalid graph value 'png'

Hi Clément,

First of all, congratulation for this great tool :smile:

Anyway, I have tried to run it with the -D flag, but it generates the following error:

Draw a threshold dotplot of two sequences

none (null, text)

Error: Invalid graph value 'png'
Died: dotmatcher terminated: Bad value for '-graph' and no prompt
Warning message:
In file(file, "rt") :
  impossible d'ouvrir le fichier './orftetable' : Aucun fichier ou dossier de ce type

I guess that the error comes from the EMBOSS's utility dotmatcher. However it still produces the pdf file with the 4 graphics. So, does it affect the results? Did I make a mistake during the installation of EMBOSS (I've installed v.6.6.0)?

Hi Tommaso!

Don't worry, all is good. I should have removed this -D option, because dotmatcher is not as good as blastn to generate the dotplot. It was here at the beginning, but more to test than anything else.

Also, when there is no ORF, the program return a warning but it keep working normally! So if you have the graphs, it means there was no real problem!

Cheers,

Clém
