|
|

|
|
*
|
|
* @bug
|
|
* There are several limitations on what type of nrrd files we can read. This
|
|
* reader only supports nrrd files in raw, ascii and gzip format. Other encodings
|
|
* like hex will result in errors. When reading in detached headers, this only
|
|
* supports reading one file that is detached.
