# Alignment tweaks
First, is the PSSS spectrum updating? If not the processing may need restarting see [contacts](Aramis Contacts)
## PSSS spectrum not updating
The most common reason for the PSSS spectrum not to be updating is the processing pipeline is not running as the camera ROI is different to the background image ROI used for background subtraction. This occurs after a camera restart as the camera ROI is not currently in a save and restore. To solve this do the following:
1. Open CamServer Management Console `csm` on console

2. Select Pipelines → Config → Filter by `PSSS` → Select `SARFE10-PSSS059_psss`
3. In the open config either set `image_background_enable` to `false` for dirty solution to disable the background or best still to check the background ROI and set the camera ROI to the required value. To do this:

1. Remember background name used i.e setting of `image_background`
1. Select Background → Filter bu `PSSS` → Select `SARFE10=PSSS059` → Select the Background image ID used in the config and read Background Size in box at the bottom
1. Set the ROI in the camera expert panel for camera `SARFE10-PSSS059` found under the Photonics Aramis tab of `camsf.ui`
Occasionally the background image ID is not listed. If this is the case a new background image should be taken. To do this first set the camera ROI to `2560x1162` (required for 100 Hz operation :disappointed:), then press the capture button in the panel shown above. The generated image ID then needs to be copied and updated in the config as described above.
