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

[Colchero, Fernando]

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

	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
