Take microarray data for example. If you've done an experiment with four time points; hours 1, 2, 4, and 8. The columns of your data set are the time points and the rows are the individual genes (see below).
# Hour 1 | Hour 2 | Hour 4 | Hour 8 |
---|---|---|---|
0.72 | 0.56 | 0.32 | 0.06 |
0.01 | 0.15 | 0.80 | 0.73 |
0.97 | 0.95 | 0.91 | 0.94 |
Loading the above data set into CompClustTk and then running a Trajectory Summary plot (see section 3.5.2), you would see that the first gene's trajectory (vector) starts high and gets lower of the four time points. Formatting your data into a tab delimited formated similar to the one shown above will allow you to load your own data sets into CompClustTk.
