Usage

Overview

ConvertType is part of GNU Astronomy Utilities 0.23. ConvertType will convert any of the known input formats to any other of the known formats. The output file will have the same number of pixels.

For more information, please run any of the following commands. In particular the second contains a very comprehensive explanation of ConvertType's invocation: expected input(s), output(s), and a full description of all the options.

If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run:

$ info help-gnuastro
