ImageJ and ROI

[Juan Francisco-2]

Dear all:
  Please: how its possible with ImageJ  to select a ROI on an image with its pixel center and ROI size determinated, whitout use the rectangular selection? I mean: it´s possible to program a command to get a ROI for center pixel and size of ROI planned?
  Thanks very much!!

Did you mean Edit / Selection / Specify ...  ?

There is the makeRectangle macro function and probably an equivalent
plugin function.
If the center point desired is (xc,yc) and the size desired is w,h. Then
x = xc-w/2
y = yc-h/2
makeRectangle(x,y,w,h)

should work.
