The file you've attached uses commas (,) to seperate the data, technically making it a csv (comma-sepeerated-value) file... despite the extension you've used.
You need to use tabs, which are usually represented as \t. If you're using a spreadsheet programing (excel/google docs etc), the tsv option may be labeled .txt instead but will probably include "tab" in the name. If you're using R/python, when you save the file, use \t as your seperator.
thank you so much for your reply.
I tried to separate the tabs and avoid using the commas, herein the file after edit. Can you please confirm me whether it's fine or not ?
Thanks a lot
I'm going to go back to. my earlier recommendations: if you're preparing this in a spreadsheet program, save it as text, if you're preparting programatically, use '\t' as your sep value.
