Sometime you do not want intermediate values but only **toggle** between max and min. Then use `-T`.
from files
----------
`i_fread <filename.tsv>` reads a line of data from the file in tsv (i.e. '0.3 0.55 0.56 ' is a vector of 3 values) and creates a channel (a vector) containing these data.
If there are many lines, it updates the data as fast as possible with each time.
It is very fast you can be either be synchronized or using **-p** to requiert a minimal time between each update.

You can also use a first column describing the time in µs to read the line.
Finaly you can limit the number of line read by using **-n**.
