In order to help researches to upload and download data to the data repository, BRICS provides the Data Repository tool that includes the following  modules (or sub-tools):
MIPAV allows you to generate intensity profiles, or contour VOI graphs, for VOI contours. For delineated VOIs, you can generate 2D, 3D, or 4D intensity graphs. You can also generate a 3D intensity graph at a specific point across all slices in a dataset. For information on how to contour a VOI, refer to Chapter 1, "Segmenting Images Using Contours and Masks,"<br />
# [[#ImagingSubmission|Imaging data submission and validation]] module should be used for imaging data to create the image submission package.
# [[#DataValidation| Data Validation]] module verifies that data conforms to the required format and range values defined in the data dictionary. It also creates a data submission package ([http://en.wikipedia.org/wiki/XML XML]) and submission ticket ([http://en.wikipedia.org/wiki/XML XML]) that can be uploaded to the data repository via the [[#DataUpload| Data Upload]] module.
# [[#DataUpload| Data Upload]] module assists researches in uploading their data to the data repository (in the form of a submission package and submission ticket).
# [[#DataDownload| Data Download]] module assists researches in downloading data from the data repository.


== Steps in data preparation, validation, submission, and download ==
=== Generating contour VOI graphs ===
'''For [[Image submission plug-in| imaging data]]:'''
Contour VOI graphs display the intensity values of the selected contour's boundary in the Contour VOI Graph window (Figure 10). You can generate either 2D or 3D contour VOI graphs. <br />
# Create and pre-validate the image submission package using the [[#ImagingSubmission|Imaging data submission and validation]] module.
# Validate the the image submission package using the [[#DataValidation| Data Validation]] module and create the data submission package/ticket using the same module.
# Use the data submission ticket from the previous step to upload the data submission package with the help of the [[#DataUpload| Data Upload]] module.
# Download the data using the means provided by the  [[#DataDownload| Data Download]] module.


'''For non-imaging data:'''
'''To generate 2D contour VOI graphs'''<br />
# Create and validate the data submission package using the [[#DataValidation| Data Validation]] module and create the submission ticket using the same module (creates automatically as soon as data pass validation).
1 Open an image.<br />
# Use the data submission ticket from the previous step to upload the data submission package with the help of the [[#DataUpload| Data Upload]] module.
2 Delineate a 2D VOI on the image using one of the 2D icons in the MIPAV window.<br />
# Download the data using the means provided by the [[#DataDownload| Data Download]] module.


== Data for upload ==
<div id="ImagingData"><div>
=== Imaging data ===
Imaging data can be uploaded in the form of a brain image file and a corresponding [http://en.wikipedia.org/wiki/Comma-separated_values CSV] file that contains some additional patient/subject/visit information (not stored in the image header) as well as image related metadata. See also [[Image submission plug-in#Required image information|Required image information]].


The following information is required for all [[Image submission plug-in|image submissions]] and must be included in a CSV file:
{| border="1" cellpadding="5"
# The patient/subject information including  - GUID, a patient/subject age, a study site name, and a visit date;  
|+ '''Figure 10. Contour VOI Graph window '''
# The image information including - imaging study date and time, imaging file name, imaging file itself, imaging file format and modality, image QA/QC information.

=== Clinical  data ===
=== Generating intensity graphs ===
In order to upload clinical data to the data repository, the data should be submitted to the [[#DataValidation|Data Validation module]] as [[Data Validation module#CSVFiles|CSV]] files (in tab-delimited format).
Intensity profiles, or graphs, present information on the intensity values of the VOI region in an image. The intensity graph appears in the Intensity Graph window (Figure 11).<br />


The [[#DataValidation|Data Validation module]] accepts [[Data Validation module#CSVFiles|CSV]] files from a researcher and validates the files' content against the values defined in the data dictionary. For  those data that pass validation, the [[#DataValidation| Data Validation module]] creates a submission package and submission ticket both in XML format.

* ''2.5D Average Intensity with Threshold'' -TBD.<br />
The Intensity Graph window (Figure 11) opens.


The submission ticket is used by the [[#DataUpload| Data Upload module]] to upload the data (in the form of a corresponding submission package) to the data repository.

The Imaging Data Submission and Validation module (also known as  MIPAV Image Submission and Validation tool or MIPAV [[Image submission plug-in]]) is designed to help researches to validate and submit their data. Data validation is a necessary step that must be done prior data submission in order to ensure the quality of uploaded data and to make data queryable. The module runs as a Java Web Start application locally on a user's computer (Java runtime environment is required).

MIPAV allows you to generate intensity profiles, or contour VOI graphs, for VOI contours. For delineated VOIs, you can generate 2D, 3D, or 4D intensity graphs. You can also generate a 3D intensity graph at a specific point across all slices in a dataset. For information on how to contour a VOI, refer to Chapter 1, "Segmenting Images Using Contours and Masks,"

Generating contour VOI graphs

Contour VOI graphs display the intensity values of the selected contour's boundary in the Contour VOI Graph window (Figure 10). You can generate either 2D or 3D contour VOI graphs.

To generate 2D contour VOI graphs
1 Open an image.
2 Delineate a 2D VOI on the image using one of the 2D icons in the MIPAV window.
