{scrollbar:icons=false} h1. Question: Can multiple users upload microarray datafiles under the same experiment? *Topic*: caArray Usage *Release*: caArray 2.X *Date entered*: 06/10/2009 h2. Details about the Question I have created a new experiment for the investigator. Now I need to transfer the ownership under me to my investigator. Can I do that? h2. Answer Yes. Multiple users can contribute the data under the same pre-published experiment. To enable this function, the experiment owner must first make the experiment sharable and assign the access right to a collaborator group: # The owner needs to change the experiment from "Draft" state to "In Progress" state by clicking *"Submit Experiment Proposal"*. # The owner grants the "Read/Write" or other appropriate role to a selected collaborator group. Refer to caArrayDemo-002 How to Use caArray to Share Pre-Publishing Data? listed under caArray Usage on the [caArray Demos] page. # Other users in this collaborator group can now upload new files to this experiment. # Different users can only access others' files after the files have been imported (that is, under the "Imported Data" tab and "supplemental file"). If a file is still in the working stage (that is, under the "Manage Data" tab), it is only accessible to its own submitter. For detailed steps on how to share pre-published data, please refer to [How to Use caArray to Share Pre-Publishing Data?|caArray Demos^Sharing_Prepublished_data.ppt] {info:title=Special Note for caArray Version 2.3 and up}Starting in caArray version 2.3, Step 1 is no longer necessary. All public visibility is also managed under *Permissions*.{info} h2. Have a comment?
