VolViewer scripting and accessing VolViewer from Matlab

VolViewer scripting

A script is a limited form of program - a list of commands. In this case the commands (http://dmbi.nbi.bbsrc.ac.uk/index.php/VolViewerScriptsAPI see VolViewerScriptsAPI]) cover most of the operations that you would usually do interactively. On Windows, VolViewer is an exe file that can either be
interactive, i.e. launched by clicking its icon or from the command prompt using the command

VolViewer.exe

or scripted. In which case the operations (commands) are stored in a script file. In which case VolViewer is launched with

VolViewer set_watchfile('file.txt')

where file.txt contains the commands. For example, if VolViewer is to be a viewing tool for an external program, e.g. a Matlab program, then the file.txt could contain

open_image_stack(0, 'E:\VOLUME DATA\ScanID1934_Leaf1\')

where ScanID1934_Leaf1 is a directory containing a stack of images.

-Normally VolViewer runs interactively this is how you would discover how best to filter and view an image stack. That done it is tedious to then repeat the operations on all stacks in a sequence. The alternative is to list the operations (commands) in a script file and tell VolViewer to follow the commands. To do this one launches VolViewer giving the name of a text file that contains the script. For example, if the script is contained in a file called '' 'myscript.txt' '' in the same path (directory) as VolViewer itself then VolViewer should be launched using the command<br>
