8/10/01 AL

The Montage from document file and Categorize from document file operations handle image stacks.

Stacked images can be displayed by specifying appropriate template (e.g. stackfile@***) for the image name

10/7/99 AL

The "Image display" operation now handles image stacks.

A single stacked image can be displayed by specifying the stacked image name (e.g. stackfile@34)

10/7/99 AL

"Pixel" and "Profile" operations work with magnified images.

The Pixel and Profile Operations now work with magnified or shrunken images.

9/14/99 AL

Montage and categorize from document file.

The filenumbers for the "Montage from document file" and "Categorize from document file" operations must be in the first register (not keys) of the document file now. It is now possible to limit the filenumbers to be displayed.

8/06/99 AL

CTF from Doc. File

A new operation "CTF from Doc. File" has been added which interactively studies the Contrast Transfer Function curve. Details.

7/06/99 AL

General Filter

A new operation "General Filter" has been added which interactively creates a mask based on a power spectrum which can be used for Fourier filtering. Details.

10/19/98 AL

Display stack images

Now, WEB can display the stack images by using "Image" operation. WEB will automatically check if the input file is a stack file or not. If "display the image name" has been selected, the image number in stack will been displayed under each image as "@012". The operation works for 2D and 3D stacks. If the file is a 3D stack file, the image number will only display once for each 3D image.

Categorize images from a montage specified in document file

The images which are used in the 'Categorize' operation can now be taken from a Document file Montage (see below) as well as a standard sequential file image montage. Details.

Montage of images specified in document file

New operation 'Montage from doc. file' makes a montage of 2-D images by looking up the image numbers in a document file. The register number cantaining the image number in the doc. file is solicited. All images must have same prefix in their name (e.g. IMA***.DAT). Can also determine, display, and save the average of all the montaged files.

6/10/96 AL

Picking markers

The 'Markers' operation has been altered to save marker locations to a doc file as soon as the marker is selected. Thus a system failure will not lose any markers which have already been picked. Details.

5/2/96 AL

Command line variables

Certain variables in Web can now be initialized from the command line or in your home directory .Xdefaults Xt resource file.

1/26/96 AL

Colored surfaces

Colored Surface Operation added. Does fast surface display of 3D file. Colors surface according to values found in asecond 3D file. Specify surface level, contribution from depth and surface reflectivity, and number of colors. The values in the color volume are divided into the specified number of colors. A private color-map can be used to alter the correspondence between colors and intensities in the color volume. Can only handle less than six colors. details.
