When creating Seeq signals using Seeq Data Lab(SDL) it can be useful to know how to delete signals from Seeq after pushing the signal to a workbench using a Spy push. Fortunately, the process is as simple as adding a column to your metadata dataframe called 'Archived' and setting the value to 'True' for any signal(s) you would like to archive. Below is a snippet of code where an 'Archived' column is added to the spy.push example notebook metadata dataframe is the SDL Spy Documentation. The DEPTH(ft) signal will be archived after pushing the new metadata dataframe with the archived column set to 'True'. A couple other notes about deleting signals in Seeq: If you would like to keep the signal in Seeq, but want to update the data, you can do so with a subsequent push of the signal that includes the new data. The caveat is the new data must have the same keys (timestamps) as the old data. If the keys are different, the data will be appended to the existing signal. Otherwise, you will need to push the signal with a unique name/path/type. If you would like to fully delete the signal samples from Seeq, you can do so using Seeq's API call to delete the signal samples.

In the course of building an analysis and experimenting you may create multiple signals and conditions you don't need. Clicking the 'x' in the Details pane will only remove them from the list but not from Seeq. As a result, when you go to create a new signal/condition and give it the same name you'll see the message 'An item with this name already exists.' This inevitably leads to the following two questions... How do I find the item? All signals and conditions can be searched for from the Data tab. Here are a few helpful hints to remember... Make sure to hit the Reset button to clear all filters and make sure you are searching from the top level and not within an asset tree. With the help of regex you can return only exact matches.... /^TAG NAME$/ For more information check out the Seeq Knowledge Base article Basic Searching and Filtering. How do I delete the item? One you find the item, add it to the Display. You can then select Item Properties and the red trash can. For more information on Item Trash check out the Seeq Knowledge Base article Item Trash.
