Error 1017 parsing the xml input file

[Javier]

Hello everyone.

I'm trying to run SNAPP via BEAST v2.6.7 but I'm getting an error that I haven't been able to figure out. Can anyone point me to the right direction?

Error 1017 parsing the xml input file

Class could not be found. Did you mean beast.core.State?
Perhaps a package required for this class is not installed?

Error detected about here:
  <beast>
      <run spec='beast.inference.PathSampler'>

Hi Javier,

The PathSamper is part of the MODEL_SELECTION package. From your post, it looks like it is not installed (neither is SNAPP). If you install these two packages the XML may run.

Hope this helps,

Remco

PS SNAPPER (https://github.com/rbouckaert/snapper) is a faster, very close approximation to SNAPP that you may be interested in as an alternative.

Hello.

I got through this error by loading the MODEL_SELECTION and SNAPP packages before calling beast in my sh file.

./packagemanager -add MODEL_SELECTION

./packagemanager -add SNAPP

./beast -threads 8 address_to_xml_file/runA.xml
