vindex − Creates the index file for a directory

vindex if=input_dir [ix=indexfile] [-a] [-sw] [-iw] [-q] [-l] [-f] [-p] [-v]

vindex both creates an index for the set of images in the input directory, and may be utilized to provide information from an index. Using vfindex to get frame information from VisionX Files it lists frame starts, so that vfclip can be used to jump directly to the exact frame. It also allows virtual grouping so that multiple DICOM files can be treated as a single VisionX file.

if=<input directory>

specifies the name of the input directory containing images in VisionX or Part-10 DICOM format.

ix=

Specifies the name of the index file to use for the image. The default is to use the index.vxi located in the same directory of the images.

-a

Switches to archival mode where the index files are written inside the directory they are indexing.

-iw

Displays the images information in tcl format. The results are the same as those returned by vdcminfo -iw, but with the added advantage that information can be retrieved on a non-existant ’virtual’ file.

-sw

Displays the scan information in tcl format. The results are the same as those returned by vdcminfo -sw, but with the added advantage that information can be retrieved on a non-existant ’virtual’ file.

-q

Displays the short listing of images in the index. The short listing is tab delimited and contains the following fields: name (may be virtual), date (in YYYYMMDD format), time (in HHMMSS format), series number, acquisition number, size (e.g. 512x512x2), resolution (e.g. 0.70x0.70x2.50).

-l

Displays the short listing of all the files in the index.

-q

Returns the full path of the index file that would be used to get information on the if= file.

-f

Forces a rebuilding of the index where the index file already exists. Normally, the index will not be rebuilt if the index file’s modification date is newer than the modification date of all of the images in the directory and no files have appeared or disappeared.

-v

Turns on verbose mode.
