Rebuild the index (or indices), typically after restarting the R session. This is because the indices are held in external memory and are not serialized correctly by R.
rebuildIndex(trained, num.threads = 1)
List containing the output of
Integer specifying the number of threads to use for training.
trained is returned with valid indices.
If it already had valid indices, this function is a no-op.
# Making up the training set. ref <- .mockRefData() ref <- scuttle::logNormCounts(ref) trained <- trainSingleR(ref, ref$label) trained$built # a valid address # Saving and reloading the index. tmp <- tempfile(fileext=".rds") saveRDS(trained, file=tmp) reloaded <- readRDS(tmp) reloaded$built # not valid anymore rebuilt <- rebuildIndex(reloaded) rebuilt$built # back to validity
