Why can't I run my pulse sequence?

There are several reasons why a pulse sequence may not run:

The sequence is not ready to be run

• If a sequence shows a grey pencil icon, it means required settings are missing.

• • Double-click the sequence to open it.

  • Set all required parameters and slice positions.

  • Save the sequence.

Once it’s ready, a gold check mark will appear, indicating it can be run.

One or more parameters are set incorrectly

If a parameter is set outside the allowed range or conflicts with another parameter, the sequence cannot be saved or run.

When this happens, the simulator will display a notification explaining what needs to be adjusted.

The sequence is not at the top of the Pulse Sequence List

The simulator runs sequences from top to bottom.

• Make sure the sequence you want to run is positioned at the top.
• Drag and drop it to the top if needed.

Another simulation is already running

Only one simulation experiment can run at a time. If a scan is already in progress, wait for it to finish before starting a new one.
