LayNii v2.4.0

Modifications

• LN2_MULTILATERATE: Speed up perimeter update. #75
• LN2_VORONOI: Add maximum distance parameter (useful for very large files e.g. 0.1 mm whole brain). #75
• LN2_COLUMNS and LN2_IFPOINTS: Now prints the maximum distance between centroids/points. Useful for understanding the approximately average distance between centroids/points. #70

New programs

• LN2_PATCH_FLATTEN_2D : For flattening 2D slices (e.g. histology data). See this video for usage: https://youtu.be/WUgaQBJkRPA14 . #71
• LN2_PATCH_UNFLATTEN: Unflattening for 3D flattened files (e.g. vitual Petri dishes, cakes ...). See the last 15 minutes of this video for and example usage: https://youtu.be/tIuKG3rtVk4 . #69

Experimental programs and changes

There are the new programs which might be modified without concerning backwards compatibility. They are highlighted in the makefile and will be removed from that section once stabilized.

• LN2_GRAMAG: Compute gradient magnitude images. Can compute phase image gradient magnitudes correctly when using circular flag. #65
• LN2_NEIGHBORS: Find 1st order neighbors of an any given input containing integers (segmentations, parcellations, custom regions of interests etc.). This program yields a comma spearated values file (.CSV) as the default output. In the future we might make use of such neighborhood information files in LayNii. #66
• LN2_UVD_FILTER: Add maximum value based depth peak detection -peak_d. We might work on the outputs and change the terminology in the future. #76
