The environment variables SCIRUN_DATA and SCIRUN_DATASET specify the complete path to a SCIRun data set. SCIRUN_DATA specifies a directory that contains a collection of data set directories. SCIRUN_DATA is used in conjunction with SCIRUN_DATASET to specify the full path of a data set. SCIRUN_DATASET specifies a specific data set directory.

When working with SCIRun's tutorial, the value of SCIRUN_DATA must refer to the sample data sets directory, SCIRunData.

for sh-type shells type:

SCIRUN_DATA=path-to-SCIRunData
export SCIRUN_DATA
      

for csh-type shells type:

setenv SCIRUN_DATA path-to-SCIRunData
      

SCIRUN_DATASET must refer to one of the data set directories within SCIRunData, e.g. utahtorso:

SCIRUN_DATASET=utahtorso
export SCIRUN_DATASET
      

or

setenv SCIRUN_DATA utahtorso
