getROI from MATLAB

[Nutan1]

Hi Everyone,

I am using Micro Manager through Matlab. I want to use the getROI function; however, it seems that its arguments are addresses and I have not been able to figure out how to handle that from MATLAB. I have tried using normal MATLAB variables as well as the pointers created through libpointer function but to no avail. Would be grateful if someone knowledgeable could point me to right direction.

Thanks,

Santosh

Hi Santosh,

I don't know how to do that in MATLAB directly, but you can use the alternative function for convenience:

gui.getROI()

This returns a java Rectangle object.

Best regards,
Arthur

Hi,


I also had Santosh question. And eventhough the gui command is an option, I prefer using micromanager directly though the core. Everything is just smoother and faster.

Hi Enrique and Santosh,

Here is the java code for gui.getROI():

   public Rectangle getROI() throws MMScriptException {
      // ROI values are given as x,y,w,h in individual one-member arrays (pointers in C++):
      int[][] a = new int[4][1];
      try {
         core_.getROI(a[0], a[1], a[2], a[3]);
      } catch (Exception e) {
         throw new MMScriptException(e.getMessage());
      }
      // Return as a single array with x,y,w,h:
      return new Rectangle(a[0][0], a[1][0], a[2][0], a[3][0]);
   }

You will need to do something similar in Matlab (including creating java arrays).

Best regards,
Arthur
