There are a number of options available to users to apply as default during their visit. These can be edited from the User Options perspective.
On opening GDA the User Options are set as illustrated above.
Autocentring takes place in two phases - the pin is found and centered using the Keyence system and then image analysis of the OAV image is carried out to find the loop and present it to the user face on.
Normal data processing is carried out routinely on samples. Where a very high volume of data is being collected we ask users to select 'light' data processing (EDNA and Fast_dp only). Please discuss with your local contact if you think this may be necessary.
By default png images are recorded for each sample. This can be turned off if you do not require the images.
On I02 there is an additional option of taking an MCA spectrum on each sample. This may enable identification of elements useful for phasing within the crystal.
Additionally, it is a default to enable to robot to mount samples as instructed by the data collection perspectives.
The final three options relate to unmaned data collection. Routinely when a sample is mounted the autocentring is followed by a pause for manual centring. To run the beamline without this pause select one of the HT modes. This will use either Keyence centring, optical centring or X-ray centring to align your sample before collecting the required images. This is very useful where the crystal size matches closely the loop size and a large beam size can be used. Please discuss operating in this mode with your local contact.
