	technologies	min_counts	min_genes	max_pct_mt	flag: min median counts	flag: min share kept	reason
group
spot	Visium, SpatialTranscriptomics	500	250	30.0	1000	0.5	A Visium or ST spot holds about 1 to 10 cells, so a spot with under 500 UMIs or 250 genes is mostly background or tissue edge; solid tissues often reach 20 to 30% mitochondrial reads, so the cap is 30%.
binned_spot	VisiumHD	200	50	30.0	200	0.5	On the 5 Visium HD sections of oliveira-2024-colorectal, 16 um bins at 200 counts kept 74% of bins with the same marker signal as 8 um bins at Oliveira et al.'s 100 (Nat Genet 57:1512-1523), which kept 60%, and found T cells in all 5 sections against 3 (web tasks/2026-11-01-t094-hd-bin-size.md).
imaging_cell	Xenium, Merscope, MERFISH	10	3	n/a	30	0.5	Targeted panels give tens to hundreds of decoded transcripts per segmented cell, and a cell with under 10 transcripts or 3 genes cannot be given a type; the panels have no mitochondrial genes.
