attachMask(object)

removeMask(object)

object

Object of class "SchemeTreeSet" or "DataTreeSet".

attachMask exports mask from scheme tree from ROOT scheme file and and saves mask as data.frame mask of slot scheme.

removeMask removes mask from SchemeTreeSet or from slot scheme of DataTreeSet and replaces data.frame mask with an empty data.frame of dim(0,0).

A DataTreeSet object or SchemeTreeSet.

Do not use attachMask unless you know that your computer has sufficient RAM, especially for exon array schemes.
