quickhash.lsm: Compute a quick hash for head and tail of a Zeiss LSM...

In jefferislab/jimpipeline: Package to wrap Jefferis lab image processing / registration pipeline

Description

The first ~ 150,000 bytes includes a number of fields such as dimension and acquisition timestamp that are typically enough to make for a unique hash. In particular the first 150K (but not 100K) are unique across the 16226 v2 flycircuit LSMs. The hope is the last 100K should include some image data (though in practice for flycircuit LSMs) this is often in the 8 bit segmented neurons which nearly all have 0 background

Usage

quickhash.lsm(f, offsets = c(0, -1e+05), chunksizes = c(150000, 1e+05), ...)

Arguments

f	Path to lsm files
offsets	Default c(0,-1e5)
chunksizes	Default c(1e5,1e5)
...	Additional arguments passed to default quickhash function

Value

character vector containing hash values for lsm(s)
