Hi,
I'm trying to run MrBayes 3.2.7 with a matrix of 37 species and 20561 nucleotides. I consistently receive the following error:
MrBayes > Execute /usr/local/Cellar/mrbayes/3.2.7/bin/19-11-2020-mrBayes-mito-prot_rrns_nuclear.nex
Executing file "/usr/local/Cellar/mrbayes/3.2.7/bin/19-11-2020-mrBayes-mito-prot_rrns_nuclear.nex"
Macintosh line termination

Defining new matrix with 37 taxa and 20561 characters
Data is Dna
Gaps coded as -
Taxon 1 -> 100010_Illex_coindetii
Unrecognized character type (0)
Error while reading character position 20562 (charCode 0)
Deleting previously defined characters
Deleting previously defined taxa
Error when setting parameter "MatrixInfo" (2)
The error occurred when reading char. 69-96 on line 2
in the file '/usr/local/Cellar/mrbayes/3.2.7/bin/19-11-2020-mrBayes-mito-prot_rrns_nuclear.nex'
There is no character in the matrix besides nucleotides and IUPAC ambiguity codes and charCode 0 error occurs just after the last character of the first sequence. I tried to change the name of the following sequence, adding spaces after it, etc and I didn't succeed. I don't understand what means the second fragment highlighted in bold since there nothing weird in that section.
Anyone had found this error. How did you solved it.
Thanks!
Hello Fernando Ángel Fernández-Álvarez could you please upload the file? Maybe looking at the file in detail I can help.
Hi Fernando Ángel Fernández-Álvarez try to convert your fasta file to nexus for mrbayes in https://users-birc.au.dk/palle/php/fabox/index.php (third one from the bottom and then open the new nexus file, delete the automatic settings for mrbayes and you can continue to work with it as with plane nexus again), good luck. Karolina
Tienes un problema con el archivo .nex, es decir que la información dentro de tu archivo no esta bien acomodada. Te recomiendo utilizar DnaSP para la transformación de tu archivo fasta a nexus.
