WFDB running in batch file

[ivo....@gmail.com]

Hello,

I am trying to run rdann in MATLAB batch mode. The goal is to run mrgann tool in background since it takes a lot of time and retrieve the result later when needed. But I am getting error with following command:

j = batch('rdsamp',2,{'100s'})

Error using parallel.Job/fetchOutputs (line 981)
 An error occurred during execution of Task with ID 1.

caused by: error using wfdbloadlib (line 114)
Undefined variable "org" or class "org.physionet.wfdb.Wfdbexec"

But following script works fine:
j = batch('rdmat',4,{'100sm'})

Thank you very much, I have already resolved it by initializing WFDB.
