What does the format of input data look like?

[shanwai1234]

The example given includes 200 nodes and 2D coordinates. I am new to Markov Clustering. I can get sequence-sequence similarity from blast for each gene pair, for example, my current data looks like below: Gene1 Gene2 60 Gene1 Gene3 70 Gene1 Gene4 65 ... Gene3 Gene4 34 How can I convert this to the format of given example in the manual? Thank you!
