[Basta-users] Errors when attempting to run multiple chains

[Graham, Jennifer]

Dear Fernando,

Thank you for your help.

These are the package versions I used: snowfall_1.84 snow_0.3-8,  BaSTA_1.2,     msm_1.1
and R version 2.14.2

Regards

Jenni

Dear Jenni,

   Thanks a lot for posting the error in the BaSTA mailing list. What version of BaSTA are you using? We had a bug in version 1.1 that usually gave that error. Would you mind installing version 1.2 and running it again? Please let us know if you get the error again; we can help you go through your data and find out where the problem might be.

   Best,

   Fernando

Hi,

I have a long-term mark-recapture dataset and the data checking function works great and I have been able to run single simulations. However when using the same data, and general model settings I get an error when I attempt to run multiple chains, I tried running with and without parallel= TRUE and I get a different error each time, see below for R Code used and errors.

Thanks for your help and a great R package.

Kind Regards

Jenni

out<-basta(DATA,studyStart=25,studyEnd=112,,nsim=4,parallel=TRUE,ncpus=4)#  I get the following error which occurs regardless  of the number of simulations I request or the ncpus value

Error in checkForRemoteErrors(val) :
 2 nodes produced errors; first error: missing value where TRUE/FALSE needed

#As I thought it could be due to the snowfall package I also ran parallel=FALSE and then get another error

Error in if (post == -Inf) { : missing value where TRUE/FALSE needed
