Description

This command provides information on the contents / type of a image file.

Examples

Example 1

Assume that you have a file, seqRecon_channel0_echo0_rep0-mag.mgh in a given directory. From a command prompt in that directory, if you execute

mri_head -identify seqRecon_channel0_echo0_rep0-mag.mgh

the command will return

succeed
mgh

This identifies the file type of seqRecon_channel0_echo0_rep0-mag.mgh. Of course, this example is somewhat trivial since the file type (MGH) is obvious from the file extension.

Example 2

Assuming again the above file, if you type

mri_head --read seqRecon_channel0_echo0_rep0-mag.mgh

you will receive

succeed
