Deleting Images

If you have issues with disk space from keeping too many images of old or un-scored drops, you can recover that disk space by executing an image management task to delete the unneeded images. In this section, you will learn different methods to delete images using both the Basic and Advanced options in Image Management.

• Deleting Images without Scores

Note

Any parameters given in the examples — such as Score Group or Min. Age of Images — can be changed according to your needs.

   Note

   If the Min. age of Images is kept at 0 days, all images matching the other parameters will be deleted.

In this section, you will learn how to delete images with scores. The following steps are designed to remove images which have outdated or uninteresting scores.

To delete images with scores:

Deleting Images with Specific Criteria

The Advanced tab is helpful when you want to delete images with specific criteria. You can select Add Constraint, Add AND, Add OR, Add NOT, and Change to OR according to your needs.

For example, in this tutorial you will use the Advanced tab for deleting images which are older than 90 days and owned by the administrator. The images in this tutorial are also scored as either “Dust” or “Clear,” and contain the protein Lysozyme.

The steps provided here are only examples. You can always modify and change the details according to your needs.

Please refer to steps 1-4 from deleting images with scores, but in this case you need to leave the Score blank in order to specify scores that you are going to delete.
