Definition

The DNA Samples tab is used to delete DNA Samples from GDM.
Only users with "Superadmin" and "Admin" roles can perform a delete action.
Users with "User" role can only view DNA Sample information using this feature, and cannot delete any information

All delete actions are permanent and will impact GDM immediately.
It is highly recommended to back up data in GDM before proceeding, as actions performed in this tool are not reversible.

Filtering

Filters are used to reduce the records displayed in the table, and users can use this feature to only display records of interest. Use two or more filters to get an intersection list of DNA Samples that meet all filtering criteria.

To filter records:

Go through each of the filters and set values in fields as desired.
Click on "Submit Query" button to apply filters.
To reset fields, click on "Clear" button. This will also clear out all filters.

Filter	Definition	Influence on other filters
DNA Sample ID, Germplasm ID	Used to get records with specific database IDs. The first field is used to get all IDs greater than or equal to the specified ID, and the second is used to get IDs smaller than or equal to the specified ID. Use the two fields together to get IDs within a range	When a value for an ID Range is specified, It's corresponding Name list is disabled. (See photos in the warning below)
DNA Sample Names, Germplasm Name	Use this filter to get records with specific names. Specify list of names with one line per name. Delimiters such as commas, colons and tables cannot be used in the list.	When a value for a Name list is specified, It's corresponding ID Range is disabled. (See photos in the warning below)
DNA Sample UUID	Use this filter to get records with specific DNA Sample UUID.	None
Projects	Use this filter to search for DNA Samples belonging to specific Projects.	None

When a value for an ID Range is specified, It's corresponding Name list is disabled. And vice versa (See photo example below)

There is a small notch/arrow right below the submit query button (between the filters panel and the result table) that you can click to collapse the filters. It will result in a bigger view of the result table.

Clicking the downward arrows, on the far right of the Filters label, will revert back to the default view.

Deleting DNA Samples

STEP 1 : FILTER

Use filters to reduce content of DNA Sample records to desired ones.
Click on checkboxes of desired DNA Sample records.

STEP 2: SELECT DNA Samples TO DELETE

Click on red "Delete Selected" button above table.
A confirmation box will pop-up with the list of files you have selected for deletion.
Click "Yes" to proceed, and "No" to abort.

STEP 3: PREREQUISITE CHECK

If "Yes" is selected, each of the DNA Samples will be checked whether or not it is associated with a DNA Run. A warning will pop-up with a list of DNA Samples that cannot be deleted and the DNA Runs with which they are associated. This list can also be exported to a file and be used as a reference.

A DNA Sample cannot be deleted if it is associated with a DNA Run

In the warning dialog, the DNA Run ID will be enclosed in a parenthesis beside the DNA Runname.
A DNA Samples can be associated with multiple DNA Runs . In which case, all the DNA Runs need to be deleted first before that DNA Sample can be deleted.

STEP 4: CONFIRM FINAL WARNING

If there are selected DNA Samples that are not associated with a DNA Run, there will be a final warning to confirm permanent deletion.

If you click "Yes", a warning will pop-up alerting you that "This action is not reversible".
If you still want to continue, click "Yes", or click "No" to abort.
If you click "Yes", the selected DNA Runs will be deleted and a pop-up of the summary will be displayed.

Deletion Summary

Upon completion of deletion, a summary page of what was deleted will be displayed and will contain:

Total number of rows deleted
Filtering criteria (This field will be empty if there was no search query performed prior to deleting the DNA Samples )
Deletion duration
