Display single SPIDER or MRC image using ImageMagick. Requires
that your system has
Imagemagick
installed and accessible as: 'convert' and 'display'.
Assumes that SPIDER images are 'Most significant byte first'
which is usually true and that the images may have
negative intensities.
Example.
.SPIDER OR MRC INPUT FILE: PIC001
[Enter name of the SPIDER or MRC image file. Does not
work with bare (whole) stacks. Automatically creates a
JPEG copy of the image with the same filename but
having '.jpg' extension. This conversion is necessary to
handle any negative densities found in SPIDER images.]
If file contains a volume SPIDER asks:
.SLICE NUMBER: 18
[Enter number of Z slice to be displayed.]
.IMAGEMAGICK DISPLAY OPTIONS (or <CR>): -resize 50%
[Enter any valid option for the
Imagemagick
display command.]
NOTES
The origin and handedness of data in a MRC is NOT
defined by any MRC file standard. It varies by software!
Thus display of a MRC image from software other than SPIDER
may yield a mirrored result.
Rapid consecutive creation and display of the same named image
may give confusing displays as the non-blocking display code
gets out of synchronization.
