Hello, I would like to know how to convert a 16-bit .tiff image to a 32-bit image for further processing. I am a new to Igor programming.
Assuming that you want to convert to a 32 bit floating point representation, type the following into the command line and execute it.

Redimension/S wavename

where "wavename" is the name of your wave.

You can also do this via the menu by selecting Data > Redimension Waves. Select the wave you want to modify (it must be in the current directory) and add it to the table in the middle of the panel. Then change the representation via the precision drop down. The text box at the very bottom of the panel will show the command that Igor will execute. This command can be executed directly from the panel (use the Do It button), sent to the command line or copied to the clipboard to be pasted in a procedure window.
