Radiomics first order stats #847

Open laurar2022 opened 1 year ago

laurar2022 commented 1 year ago

Hi, i have loaded a structure from a RT DICOM file to modify it. But after doing so, the first order features i get from the function radiomics_first_order_stats are the same as when the structure wasn't modified. I don't know if CERR isn't saving the changes I'm making to the structure, but every time I modify it I click save. Still the first order features don't change.

Perhaps you can check whether you get a different volume for the modified structure using the following. Make sure to use "global planC" to get changes from the GUI.

global planC

% Structure volume getStructureVol(structNum,planC)

% Obtain first order statistics offsetForEnergy = 1000; % For CT, for example. Can be set to 0 for PET, MR. binWidth = 10; binNum = []; firstOrderS = radiomics_first_order_stats(planC,structNum,offsetForEnergy,binWidth,binNum)

There were updates to this routine to accept number of bins for entropy calculation. Please pull the latest updates.

I've checked the volume with getStructureVol and it changes when modifying the structure, however first order stats remain the same. I've checked I have the updated version from 2018 and I'm using global planC.

radiomics_first_order_stats accepts structure and scan index from planC or the structure and scan matrices. You will have to pass scan and structure index to radiomics_first_order_stats so that it uses the modified structure from planC.
