'''nipy_diagnose will generate a series of diagnostic images for a 4D
fMRI image volume. The following images will be generated. <ext> is
the input filename extension (e.g. '.nii'):
* components_<label>.png : plots of PCA basis vectors
* max_<label><ext> : max image
* mean_<label><ext> : mean image
* min_<label><ext> : min image
* pca_<label><ext> : 4D image of PCA component images
* pcnt_var_<label>.png : percent variance scree plot for PCA
components
* std_<label><ext> : standard deviation image
* tsdiff_<label>.png : time series diagnostic plot
The filenames for the outputs are of the form
<out-path>/<some_prefix><label><file-ext> where <out-path> is the path
specified by the --out-path option, or the path of the input filename;
<some_prefix> are the standard prefixes above, <label> is given by
--out-label, or by the filename of the input image (with path and
extension removed), and <file-ext> is '.png' for graphics, or the
extension of the input filename for volume images. For example,
specifying only the input filename ``/some/path/fname.img`` will
generate filenames of the form ``/some/path/components_fname.png,
/some/path/max_fname.img`` etc.
