Function try to load 'fst' arrays, if not found, read 'HDF5' arrays

Usage

load_fst_or_h5(
  fst_path,
  h5_path,
  h5_name,
  fst_need_transpose = FALSE,
  fst_need_drop = FALSE,
  ram = FALSE
)

Arguments

fst_path: 'fst' file cache path
h5_path: alternative 'HDF5' file path
h5_name: 'HDF5' data name
fst_need_transpose: does 'fst' data need transpose?
fst_need_drop: drop dimensions
ram: whether to load to memory directly or perform lazy loading

Value

If 'fst' cache file exists, returns LazyFST object, otherwise returns LazyH5 instance

Details

RAVE stores data with redundancy. One electrode data is usually saved with two copies in different formats: 'HDF5' and 'fst', where 'HDF5' is cross-platform and supported by multiple languages such as Matlab, Python, etc, while 'fst' format is supported by R only, with super high read/write speed. load_fst_or_h5 checks whether the presence of 'fst' file, if failed, then it reads data from persistent 'HDF5' file.
