Within the QMENTA Platform, the uploaded image data can be processed in order to obtain a particular set of output data, or results. The image processing tools used, whether implemented in singular units or organized into Workflows, are collectively termed analyses.
You may execute already available, in-house analyses, or integrate and execute your own. The processes involved in both of these are described below.
Starting an Analysis
To start an analysis, first go to the “Analysis” tab:
Click “Start Analysis”:
A pop-up window will appear on the screen:
From within the window above:
- Select the analysis type you want to run.
- Modify the name of the analysis for that particular execution (optional).
- Select the input data you want to analyze (see figure below).
- Configure the settings to customize the analysis (optional, and if applicable).
- Click “Start Analysis”.
Alternatively, analyses can be started directly from the “Data tab” on the Dashboard (see figure below). Check the row of the pair Subject ID/Session ID of interest and click “Start Analysis”. By checking multiple sessions, multiple analyses can be scheduled at once. Note that, by batch starting analyses in this way, it will not be possible to customize the analysis settings to the requirements of individual data sessions should they differ. 
Using either of the previous approaches to start an analysis, if the data requirements for the analysis are matched by multiple files within the session a pop-up window similar to the figure below will appear to facilitate selection of the desired input data.
The previous pop-up window might even appear in the cases where the input modality is optional as is the case of the analysis shown in the next figure (see T2 image modality). As explained, it is due the presence of repeated files that satisfy the input requirements of the analysis. In these cases, the selection of the “optional” input file is mandatory for the analysis to start, however, the analysis window will include a setting to indicate if those optional files are to be used as input of the analysis or not.
On the contrary, if the required data for the analysis is not present among the data available in the session a pop-up window with a warning will appear as shown in the figure below.
The QMENTA Platform will schedule the analysis to run automatically as soon as the necessary resources are available.
The status of an analysis may be consulted in the “State” column of the “Analyses” tab as shown in the figure below:
- A blue triangle indicates that the analysis is still running.
- A green circle indicates that the analysis has completed successfully and the results are available for viewing.
- A red circle indicates that the analysis did not complete successfully.
- A blue silhouette figure indicates that the analysis involves a Manual Step and is awaiting user action.
- A gray circle means the analysis is pending to be executed.
