You need to make a text file with these details for each marker:
- ref_snp: ideally the rs number from dbSNP but you can supply any name you wish. It must not exceed 10 characters or contain any spaces.
- coord: ideally the chromosomal coordinate but this can be any number not exceeding 10 characters.
- each marker is listed on a new line
- markers must be ordered by coordinates, from lowest to highest
- the first line gives the fieldnames in this order: name, coord
- the fields are separated by tabs
On the data entry page you'll find a utility to help your format your marker list. Alternatively you can generate the required format by making two columns in a MS Excel
spreadsheet, with the fieldnames on the first row, and the values for each marker on a separate row. When you have finished, click:
File > Save as.. > Save as type > Text (tab delimited)
Example:
ref_snp coord
rs9875432 38765432
rs9845257 38765498
TNF-308 38765543
rs8765432 38795977
Don't worry if the columns don't line up nicely (this will depend on your text editor) as long as there's a single tab between each field.
