Edit the script and remplace all the "WD" by your working directory:

 

Here, an example of script:

############################################

# Common
############################################
# fixed information on script -> mandatory
LIFEx.script = MTV
LIFEx.script.version = 1.0
# result file -> mandatory
LIFEx.output.file=WD/MTV_results.csv
########################################################################
# patients / ROI #
########################################################################
LIFEx.Session0.Img0=WD/PT1/IMG
LIFEx.Session0.Roi0=WD/PT1/ROI/R1.uint16.nii.gz
LIFEx.Session0.Roi1=WD/PT1/ROI/R2.uint16.nii.gz
LIFEx.Session0.Roi2=WD/PT1/ROI/R4.uint16.nii.gz
LIFEx.Session1.Img0=WD/PT2
LIFEx.Session1.Roi0=WD/PT2/ROI/R1.uint8.nii.gz
LIFEx.Session1.Roi1=WD/PT2/ROI/R2.uint8.nii.gz
LIFEx.Session1.Roi2=WD/PT2/ROI/R4.uint8.nii.gz

 

Here, an example of result:

INFO_PatientName    INFO_PatientID    INFO_PatientWeight(Kg)    INFO_ProcessDateOfTexture      INFO_SeriesDate    INFO_Series                 TLG(SUV*mL)    sTLG(SUV*mL/Kg)    MTV(mL)    sMTV(mL/Kg)    Dmax(cm)    sDmax(cm)    DmaxVox(cm)
