A lock file in the cache directory avoids simulatneous write and read. It's supposed to be removed after each read and write operation. This might not happen if the process crashes during such an operation. In this case you can manually call this function.

## Usage

omnipath_unlock_cache_db()

## Value

Logical: returns TRUE if the cache was locked and now is unlocked; FALSE if it was not locked.

## Examples

omnipath_unlock_cache_db()
#> [1] FALSE
