filterTrack(trackll,filter=c(min=7,max=Inf))
trimTrack(trackll,trimmer=c(min=1,max=32))
trackLength(trackll)

`trackll`	a list of track lists.
`filter`	range of possible track lengths to keep
`trimmer`	range of track lengths allowed in output, otherwise trimmed.

filterTrack() is used to filter out tracks that has length within a specified range (default 7~Inf). On the other hand, despite the lengths of tracks, trimTrack() is used to trim /cutoff all tracks to a specified range (default 1~32).

trackll filtered or trimmed tracks.
len list of track lengths.

trackll=createTrackll(folder=folder, input=3)

trackll.filter=filterTrack(trackll,filter=c(7,Inf))
trackll.trim=trimTrack(trackll,trimmer=c(1,20))

# see the min and max length of the trackll
# trackLength() is a helper function output track length of trackll

lapply(trackLength(trackll.filter),min)
