roi intensity graph with array indexing

[megastar]

Hello.. I managed to select ROI of intensity graph with two cursors and array index function. But new ROI 2D array indexing starts from zero. I need to make ROI along with array indexing values. I mean it should not start from zero and maintain same indexing as before ROI. Please help me..  Thank you

Hi,

you could always initialize a 2D array with the same dimensions as the original one and insert the ROI 2D array. I don't see why you would want to do that though.

Maybe we're not at the core of the problem.

Another thought: You could store the starting indexes of the ROI and use that info to convert index values.

Could you post your code so far and elaborate on what you are trying to achieve. More big picture, you were asking about a detail - perhaps the approach that necessitates that detail is flawed.

Regards

Florian
