complement-fieldsclj
(complement-fields refs xs)Takes a sequence of maps containing :name and :len keys (representing chromosome's name and length, resp.) and a sequence of BED fields, and returns a lazy sequence that is the complement of the BED sequence.
The input sequence will first be sorted with sort-fields, which may cause an extensive memory use for ones with a large number of elements. Note also that this function assumes the BED sequence contains only valid regions, and thus :start <= :end holds for each region. Make sure yourself the BED sequence meets the condition, or the function may return a wrong result.

intersect-fieldsclj
(intersect-fields xs ys)Returns a lazy sequence that is the intersection of the two BED sequences.

merge-fieldsclj
(merge-fields xs)Sort and merge overlapped regions. Currently, this function affects only :end and :name fields.
Sort and merge overlapped regions. Currently, this function affects only :end and :name fields.
read-fieldsclj
(read-fields rdr)Returns a lazy sequence of normalized BED fields.
Returns a lazy sequence of normalized BED fields.
readerclj
(reader f)Returns an open cljam.io.bed.BEDReader of f. Should be used inside with-open to ensure the reader is properly closed.
Returns an open cljam.io.bed.BEDReader of f. Should be used inside with-open to ensure the reader is properly closed.
sort-fieldsclj
(sort-fields xs)Sort BED fields based on :chr, :start and :end. :chr with common names come first, in order of (chr1, chr2, ..., chrX, chrY, chrM). Other chromosomes follow after in lexicographic order.

subtract-fieldsclj
(subtract-fields xs ys)Returns a lazy sequence that is the result of subtracting the BED fields in the sequence ys from the sequence xs.
The input sequences will first be sorted with sort-fields, which may cause an extensive memory use for ones with a large number of elements. Note also that this function assumes the input sequences contain only valid regions, and thus :start <= :end holds for each region.

write-fieldsclj
(write-fields wtr xs)Write sequence of BED fields to writer.
Write sequence of BED fields to writer.
writerclj
(writer f)Returns an open cljam.io.bed.BEDWriter of f. Should be used inside with-open to ensure the writer is properly closed.
