Finding Array Design Files

No array design information is present with a new caArray installation. This feature provides the flexibility for an organization to upload only the designs they use. This reduces the overhead introduced by loading unnecessary designs - , which are often of significant size (100's of megabytes or more). This does mean, however, that users must find and upload all the necessary array design files into their caArray server. Searching for the array design files could be confusing and time consuming.

Many It is possible, if you are not using a new instance of caArray, that the array design file you need already exists in caArray. For example, many array design files have been uploaded into NCI's caArray by the users, and they can be reused for other experiments on the same server.
