Signal subtraction

What do I need?

This protocol assumes that you have run Meridien.


Average and Filter
Average and low-pass filter a map for segmentation.
Segment Filtered Map
Display the map in Chimera, and locate regions to be subtracted.
Generate and Apply Mask
Make a soft mask of the region to be excluded.
Project and Subtract
Compute re-projections of map to be subtracted, and subtract them from the original images.
Compute 3D Reconstruction
Compute a 3D reconstruction using refinement iteration used for signal-subtraction.
Center Map
Center map of remaining density.

What do I do next?

Once these steps have been completed, perform a restricted refinement.
