How to upload TMA data (anonymous users)

The process of uploading a dataset consists of two steps which are described in the sections below. Briefly, the first step is to supply a file containing marker values (typically TMA protein expression scores); the second step involves selecting options to be applied during the upload and providing information about the dataset (e.g. a title). When the dataset is uploaded, it is added to a queue for processing. You can then either wait until processing completes (usually a few moments depending on file size), or bookmark the page in your web browser for a later visit. Once processing has completed successfully, the dataset is ready for analysis. The help section data requirements - marker scores gives information on how to organise your TMA data for successful uploading.

You can upload data using the Add dataset button on the top right of every page (figure 1).

Warning: Datasets uploaded by anonymous users and associated results will be deleted after six months. Please be sure to save any data you need within the six month period.

Stage 1: File validation

From the home page, click on Start workflow. You will now be on a page titled Upload a dataset.

To begin, click on the button in the middle of the page labelled Upload data (figure 2). The add dataset form will then appear (figure 3).

You can also access the add dataset form from any page on the site by using the Add dataset button in the top right (figure 1, above).

With the add dataset form open (figure 3, above) click the button labelled Upload a file. You will then be asked to choose a file from your computer. Once you have selected a file, click OK. The file is then uploaded to the site and validated. The message Loading will appear with a progress bar. Please wait for the file to upload, even if the progress bar doesn't move. This process should only take a few moments.

Once the file is uploaded, it is validated (checked against data requirements). An error message is given if the dataset doesn't validate successfully - for example, if any scores are not numeric, or marker identifiers contain disallowed characters. If you get a validation error message there will be information included about how to modify your input data in order to pass validation. For details on the acceptable file formats and how to lay out your data, please see data requirements - marker scores. Please contact us if you require guidance on validating your data.

Stage 2: Data annotation and processing

Once the file has been validated successfully, you will be asked to enter a few details and select processing options (figure 4). The options on the form are as follows:

When the above has been completed, click the Save dataset button.

Having clicked the Save dataset button, you will be redirected to a unique page for the dataset (figure 5). The dataset is added to a queue for processing, which typically takes just a few moments. Importantly, in order to return to the dataset, bookmark this page or make a note of the web address (URL). The URL contains a unique key which is needed to view the dataset.

Once the processing has completed, the dataset is ready and options for running analyses are made available.

If an error occurs during import, a message will be displayed that includes guidance on how to resolve the error. The help section on dataset error messages gives further information.
