There are right now some limitations with compatibility to e-film workstations. K-PACS can query E-film on study and series level. For exact matching keys you have to add a wildcard character '*' to override the general wildcard k-pacs appends automatically. For partial matching keys don't add '*'.
Pushing images to e-film and visaversa does work, but pulling images from e-film fails right now. Maybe I can fix that, but for all of you who use e-film as a server: better change to a real server with a performant database like conquest. It is far better configurable, more stable and can handle millions of images with MySQL or even the new internal DBIII driver. The internal efilm database should be used as a cache for the most recent studies.
