V33 (1 of 2): upload long-range interaction data
Friday, March 7, 2014
From version 33 you can now upload long-range interaction data in the form of text files. This is very suitable for showing small quantity of data (including but not restricted to 5C, ChIA-PET, Hi-C results), and you don't need to go through trouble of converting your data into the required format and host it as a custom track.
To start, convert your data into a simple format like this:
chr1,713605,715737 chr1,720589,722848 2 chr1,717172,720090 chr1:761197-762811 2 chr1,755977,758438 chr1:758539-760203 2
Each line indicates an interaction event involving two regions from the genome. 3 fields are present for each line: coordinate of region 1, coordinate of region 2, score.
For the coordinates, you can use a non-word character to separate fields, but don't use tab. The score is optional. Unlike that is required for the long-range interaction track format, do not make duplicating records for each of the interacting pairs.
Go to Apps > File upload:
Upload your file. At the "Edit" panel, choose "Pairwise interaction" option and click "Add" button. The track will be loaded:
