I have found an error while creating spatial, band and tie-point grid subset in one step (from Raster menu => Subset). It occurs with every image I tried on different PCs. To reproduce this problem, I am adding some screen shots. My question is, why it occurs?
The error is seen while creating the subset in one process. If you split it to at least two processes, the result is as expected. For example, band + tie-point grid subset in one process and spatial subset in another.
Thank you for your response.
