What does the --closure-search option of TopHat do?

I'd also really like to know what this does. I have some sequence data from PE reads with a range of fragment sizes. If some of the reads meet the criteria for the expected inner distance between mates to be <= 50 bp, but some do not, does anyone have an idea how this would affect mapping? -
From tophat manual:
I believe it has to work with the following, but haven't test yet.Code:--closure-search Enables the mate pair closure-based search for junctions. Closure-based search should only be used when the expected inner distance between mates is small (<= 50bp)
Code:--min-closure-exon During closure search for paired end reads, exonic hops in the potential splice graph must be at least this long. The default is 50. --min-closure-intron The minimum intron length that may be found during closure search. The default is 50. --max-closure-intron The maximum intron length that may be found during closure search. The default is 5000.

Perhaps I should be more specific.

Did one of you guys find out what this does? I am also curious.Comment

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
