Introduction

When manuscripts are submitted for publications, many journals require the microarray data associated with the manuscripts to be made available to reviewers in a MIAME compliant format.

caArray can help users to meet this requirement by offering: • Fast & easy MAGE-TAB compliant data upload to caArray server.• Flexible access control: User can grant or revoke the reviewers’ access rights to user’s

private experiments.

• Data can be stored in user’s local caArray server or in NCI’s public caArray server (https://array.nci.nih.gov/caarray/home.action).

This presentation will show you how to use caArray to grant read/revoke access on an unpublished experiment to reviewers.

User Account Prerequisite

There are two previously created caArray user accounts used in this presentation:

• User Account – An account used to create & submit the experiment• Caarrayuser (in this presentation)

• Reviewer’s account – An account to be used by reviewers to access user’s private data (a read only account)

• CU_reviewers (in this presentation)

4

Permission at Group Level

Since the permission on experiments can only be granted at the collaboration group level, We will first:

1. Create a new collaborator group, called “Reviewers”, under user account: “caarrayuser”.

2. Assign reviewers’ account, “CU_reviewers”, to be a member of this new collaboration group “Reviewers”.

5

Create A New Collaborator Group

To create a new collaborator group:

1. Click on “manage Collaborator Groups”

2. Click on “Add a New Collaboration Group”

3. Assign an unique name for the group. “Reviewers” is used in this presentation.

6

Assign Member to a Collaborate Group

To assign reviewer’s account: ” CU_Reviewers” to be the member of the group :• Click on “Edit” button for collaborator group “Reviewers” as shown by arrow.

7

Add New Members to a Group

Find and add users to be member(s) of this new group:1. Click on “Add a New Group Member” bottom. 2. Enter registered users last name, first name, or organization, click the “Filter” button to find the user3. For each member to be added to the group, click the Add icon (+) in the far right column of the screen.

Different Views of A Private Experiment

8

• A private experiment in “Draft” status (“user-00028” , Figure 1) is shown as “Not Available” to public (Figure 2).

9

Draft Experiment Is Not Sharable.

When the experiment is created, it is defaulted to be in “Draft” state, which is only accessible to its creator. To share this experiment with other users, this experiment must be submitted to a sharable area first.

To share the private experiment “User-00028”, click on the name to open the experiment as shown by arrow.

10

Submit Experiment Proposal

• Click on “Submit Experiment Proposal” button.• The status of experiment “user-00028” will change from “Draft” to “In progress” status.

11

Change Experiment’s Permission

Experiment “User-00028” is now in sharable “In progress” state.

To assign the read-only permission to a collaborator group, • Click on permission icon under “Permissions” as shown by arrow.

Assign Collaborator Group to The Experiment

• Change collaborator group to be ‘Reviewers” as indicated by the arrow.

13

Grant Access Role to A Collaborator Group

To grant the access:

1. Click on “Edit Access Control” at the lower left corner.

2. Use drop down list at the right to assign permission to choose the access.

3. Assign “Read” to the collaborator group, “Reviewers”.

4. Click on “Save” button.

14

Private Data is Sharable

•Re-login with reviewers’ account : “CU_reviewers”.•Click on “Browse” at left menu to open the list of experiments. •“CU_reviewers” can read annotation information and download array data from Experiment “user-00028” .

15

Revoke Access Role to A Collaborator Group

To revoke the access, go back to permission access page:1. Click on “Edit Access Control” at the lower left corner.2. Use drop down list at the right to assign permission to choose the access.3. Assign “None” to the collaborator group, “Reviewers”.4. Click on “Save” button.

You may also revoke the access by deleting the collaborator group.
