Spatial omics have transformed tissue architecture and
18+
cellular heterogeneity analysis by integrating molecular
19+
data with spatial localization. In spatially resolved
20+
transcriptomics, identifying spatial domains is critical
21+
for analysis of anatomical regions within heterogeneous
22+
datasets and understanding tissue function. Since 2020,
23+
more than 50 spatially aware clustering methods have been
24+
developed for this task. However, the reliability of
25+
existing benchmarks is undermined by their narrow focus on
26+
Visium and brain tissue datasets, as well as the
27+
dependence on questionable ground truth annotations. Here,
28+
we implemented a consensus framework that surpasses
29+
traditional benchmarking practices.
30+
31+
32+
Our framework comprises a community-driven benchmark-like
33+
platform that streamlines data formatting, method
34+
integration, and metric evaluation while accommodating new
35+
methods and datasets. Currently, the platform includes 22
36+
spatially aware clustering methods across 15 datasets
37+
spanning 9 technologies and diverse tissue types. The
38+
benchmark approach uncovered significant limitations in
39+
generalizability and reproducibility where methods that
40+
perform well on healthy tissues often falter on cancer
41+
samples. We also found that anatomical labels commonly
42+
used as ground truths are often biased, potentially
43+
error-prone, and in some cases, unsuitable for
44+
benchmarking efforts.
45+
46+
47+
In light of these issues, we adopt a flexible
48+
expert-in-the-loop consensus-driven approach. This goes
49+
beyond traditional ensemble/consensus methods, and allows
50+
researchers to interact with intermediate results to
51+
determine which tools should be used to generate a
52+
consensus. We believe that the inclusion of an
53+
expert-in-the-loop is critical to ensure that the
54+
computational analysis matches the biological question at
55+
hand, and we believe that when the focus of the analysis
56+
is to un cover novel biological discoveries, tissue
57+
experts are accessible more often than not.
