## Save Tab

Use this tab to:

- Save annotation notes into your metadata files.
- Set where to save and what to name the output data files.
- Check the available disk space, hence, maximum possible recording time.

## Run Name and Run Continuation

You can set the name for your run either in this tab’s `Run name` box or in the run toolbar at the top of the Graphs window. In the Graphs window you must first pause writing via the optional `Enable/Disable Recording` button as described here.

Both of these inputs accept either an undecorated base-name for a run, or a decorated name of the form `run-name_gN_tM`. The decorated form tells SpikeGLX you wish to continue writing additional files into an existing run, starting at the specified g/t indices. This is very useful if a run had to be interrupted to repair a problem.

Note too, that you can change to a different run name without stopping the run. Use the Graphs window `Disable` button to pause writing, then type in a new undecorated name (no g/t indices). This will be treated as a request for a brand new run name that will start at _g0_t0.

### Unique Name Rules

If the run name is undecorated, the provided base-name must be unused in all of the current `Data Directories`.

If the name is decorated, then those indices must be unused. That is, `run-name_gN_tM` must not exist in any of the current `Data Directories`.
