This output file has information +about clusters and coordinates of LTR retrotransposons identified. Each cluster of LTR +retrotransposons starts with the head line of [cluster_number]---------, followed by +the information of LTR retrotransposons in the cluster. The columns for LTR +retrotransposons are as follows. + +1. LTR_id: unique id of LTRs identified. It consist of two components, sequence file name and id in the file. For example, chr1_2 is the second LTR retrotransposon in the chr1 file. +2. start position of 5 LTR. +3. end position of 5 LTR. +4. start position of 3 LTR. +5. end position of 3 LTR. +6. strand: + or -. +7. length of 5 LTR. +8. length of 3 LTR. +9. length of the LTR retrotransposon. +10. TSD on the left side of the LTR retotransposons. +11. TSD on the right side of the LTR retrotransposons. +12. di(tri)nucleotide on the left side of 5LTR +13. di(tri)nucleotide on the right side of 5LTR +14. di(tri)nucleotide on the left side of 3LTR +15. di(tri)nucleotide on the right side of 3LTR + +License +============ + +Copyright 2014 Mina Rho, Haixu Tang. +You may redistribute this software under the terms of the GNU General Public License. + +
