Once you successfully save a sample to the database, you or the data curator can generate a data availability metrics table for the sample. The metrics identify the percentage of data available for the sample and displays metrics of submitted data against caNanoLab-supported data and data supported in the MinChar standard.

Curators and batch metrics

A data curator can generate data availability metrics in batch mode for samples as well.

Reviewing the Metrics for an Individual Sample

To review data availability metrics for an individual sample

  1. Perform a sample search.

  2. From the sample search results, if data availability metrics are generated for a sample, click the link in the Data Availability column

    Data Availability Metrics link in Sample Search Results

You can review the metrics and click Close when you are done.

Re/Generating Metrics for an Individual Sample

To delete or regenerate availability metrics for a sample

Updating a public sample

If you generate data availability metrics after a sample is made public, the updated metrics will not be included in the public version. You will have to submit the sample for review again, as described in Making a Sample Public.
  1. Perform a sample search.
  2. From the sample search results, click Edit in the Actions column. The Update Sample page opens with the Data Availability Metrics section at the bottom.
    Data Metrics Availability section of Update Sample
    1. If there are no metrics generated for the sample, click Generate.
    2. If metrics were previously generated, click Edit.
    The metrics table displays high-level metadata. 
    Top of Data Metrics Availability dialog box.

    For example, the following table describes the percentages at the top of the metrics table.

    Percentages at the Top of the MetricsDescription
    caNanoLab Availability Score: 10.0% (3 out of 30)Indicates that the sample has 10% of the total possible number of caNanoLab attributes filled in or 3 out of 30.
    MINChar Availability Score: 11.0% (1 out of 9)Indicates that the sample has 11% of the total possible number of MinChar attributes filled in or 1 out of 9.

    The following table describes each column on the metrics table.

    Columns in the MetricsDescription
    caNanoLabLists all data elements that can be added to the sample in caNanoLab.

    MinChar

    Lists the minimum nanoparticle characterization standards as established by MinChar Initiatives.

    [Name of sample]includes check marks where data element annotations are added to the sample.
  3. When you are done viewing the metrics, choose one of the buttons at the bottom of the metrics table.
    caNanoLab Data Metrics Buttons
    1. Click Delete to delete the metrics for this sample.
    2. Click Regenerate to regenerate the metrics.
    3. Click Close to return to Update Sample without changing the metrics.
