validate_store: Check an on-disk STlist against its manifests

Source: R/store_parquet.R

Verifies that a backed STlist's files exist and still match what its manifests record, reading parquet footers only.

validate_store(x = NULL, deep = FALSE)

Arguments

x

a backed STlist

deep

logical, whether to read data pages as well as metadata

Value

invisibly TRUE, or stops with the first problem found

Details

Checks sample order against the recorded sample_order (fidelity rule 7), that every file exists and its size/mtime fingerprint is unchanged, that dimnames lengths agree with the recorded dimensions, and that @tr_counts genes and cells are subsets of @counts' in the same relative order – the invariant filter_data() assumes. With deep=TRUE, also reads the data to check index bounds and duplicate coordinates.
