Finds all intervals where track expression is 'TRUE'.
gscreen(
expr = NULL,
intervals = NULL,
iterator = NULL,
band = NULL,
intervals.set.out = NULL
)logical track expression
genomic scope for which the function is applied
track expression iterator. If 'NULL' iterator is determined implicitly based on track expression.
track expression band. If 'NULL' no band is used.
intervals set name where the function result is optionally outputted
If 'intervals.set.out' is 'NULL' a set of intervals that match track expression.
This function finds all intervals where track expression's value is 'TRUE'.
If 'intervals.set.out' is not 'NULL' the result is saved as an intervals set. Use this parameter if the result size exceeds the limits of the physical memory.
