| Raw, unregistered 8-bit tiff series |
| Details: Serial 250 nm resin tissue sections. Image capture resolution = 476 nm/pixel. Post-cap operations: INVERT Images with B, TT and E signals are easiest to align. G is the most difficult in this set Capture Series (Win: right-click > save as; Mac: Ctrl-click, save as) |

![]() ↑ PCI = 11 classes Full size indexed tiff: Marc_2366_original_PCI_map.tif ![]() ↑ Morphias = 9 classes Full size indexed tiff: Marc_2366_morphias_map.tif ![]() ↑ Morphias-PCI: The class match is excellent overall and argues that Morphias is already a good substitute for PCI. This is a difference map between Morphias and PCI (after median filtering to correct for some kerf errors). The purple class is a separate PCI class contained mostly within the orange class in Morphias. The blue class is a separate PCI class is contained mostly within the lite green class in Morphias. We compared some (not all) signals in CellKit as 2D histograms for these classes with the conclusion that PCI pushed the envelope a bit, while Morphias was conservative. Of course we restricted clusters to 12 and haven't given Morphias a fair test yet. We also haven't used mindis to assess separations. Maybe by the end of next week.
