Description

Protocols are free text descriptions of the procedures, techniques that were used in processing a sample during individual steps of a microarray experiment.

A Protocol has a

 
Name: The name should be unique and max. 120 characters long.
Protocol Number: A number unique to a protocol. Used by the database and not accessible to users.
Description: The description of the protocol. This should be plain text (that can be formatted) and max. 4000 characters long. A protocol must contain a description to be accepted by the database.
URI: Optional web-address of the protocol if available.
Procedure: A protocol must be associated to a procedure existing in PUMAdb (see Procedures for a list of the available Procedures).
Owner: The userid of the owner of the protocol.
 
Protocols can be created by
Enter Protocol and existing protocols can be viewed and edited using List Protocols.

Entering New Protocols

A new protocol can be created by Enter Protocol. The fields Protocol Name, Procedure and Description are required. The owner of the protocol is created automatically and is the user who entered the protocol (this can be changed during editing of the protocol).

Editing/Cloning an Existing Protocol

A protocol can be either edited or cloned. During 'cloning', a second protocol is created based on a previously existing one. The new protocol must have a new, unique name to be accepted by the database. No new protocol is created during 'editing', but an already existing protocol is modified.

Only the owner of the protocol can 'edit' the protocol and only if no other user associated experiments to the protocol. If such a shared protocol needs to be modified, please contact the curators at: array@princeton.edu, they can do this for you. If a user can see the protocol (s)he can also clone it.

A protocol can be edited/cloned after selecting the appropriate 'edit' icon on the list of available Protocols. The same constraints as the ones listed above apply: the resulting protocol name has to be unique; description, userid, name are all required; the length of the fields should be less than the allowed limit.

Deleting a Protocol

Only the owner of the protocol can 'delete' the protocol and only if no other user associated experiments to the protocol. To delete a protocol 'in use', first its associations to experiments need to be removed. To delete a protocol that is not associated with experiments, select the appropriate 'delete' icon from the list of available Protocols. After confirmation, the protocol is deleted from the database and cannot be retrived.

Access to Protocols

The List Protocols program lists all the protocols a user has permission to see. Users can see their own protocols or protocols of other members of their default lab group. Additional access to protocols is determined by access to experiments: if a user has view access to an experiment, (s)he can also see the protocol associated to the experiment.
