Subject: extracting images from the Signa
Each time that you run ximg to get images from the Signa system, the software creates a COPY of those images. This rapidly fills up disk space. To make mattesr worse, the default behavior of the Signa is to store these files on the Signa system disk in teh directory, /usr/g/insite/tmp
When that disk becomes full the scanner cannot operate. It is therefore imperative that you remove any files from the Signa that you create using ximg.
To do this, after you are done extracting your images, open a telnet or xterm to the Signa, then,
| genesis @ UC3T_OC0 1: cd /usr/g/insite/tmp genesis @ UC3T_OC0 2: rm EXXXX*.MR |
(note that EXXXX*.MR refers to all images of the XXXX study number)
One useful alternative is to set up the environment variable, EXTRACT_IMAGE_DIR to point to a disk other than the Signa system disk. This way, the extracted images will appear on your choice of volumes. For example, before running ximg, you might do this:
| imexport@UC3T_OC0: mkdir /space/mydata imexport@UC3T_OC0: setenv EXTRACT_IMAGE_DIR /space/mydata imexport@UC3T_OC0: ximg -i E1040S3Iall -t -s |
by so doing, the extracted images will appear in the newly created directory, /space/mydata rather than on the Signa. Please be careful about this, as we have been having increasing trouble with adequate disk space on the scanner. Unfortunately, they will be owned by root...
