Start by opening the Multiscan module on the toolbar.
If you wish to run a multiscan on a tall specimen, where the individual scans can be stitched together, you'll need to first specify the top and bottom limits of the specimen.To do this, right click and turn on the cross hairs and position your specimen so that the top (or bottom) is at the middle of the screen. When you have one end positioned, click Add Position in the Multiscan module, then repeat for the other end. Once the top and bottom are defined, click Complete for the computer to calculate the intermediate scans.
Alternatively, you can define multiple scan levels without using the Complete button to get multiple independent scans. Note that Datos will not be able to stitch these together.
Disable collision detection (after checking that there will be no collisions) and start scan as normal from here. If a dialogue asks you to overwrite the position, click no. A Multiscan will result in separate files labeled "Scan1," "Scan2," etc under your defined directory.
Instead of opening the main .pca file, you must go into the “scan 1” folder and open the .pca there. Do not click AGC yet. You may crop here, but be careful since cropping at the sides will extend to the other scans. Go to Modules > Multiscan and do an AGC for each scan where given the option. Very large Multiscans may take a lot of time to reconstruct and may even crash the computer if large enough.
