Dear experts,
I am sorry that I am not familiar with the usage of Rootana.
I cannot find any detail instructions or tutorial about this package.
I hope that the instructions or tutorial can be added. 

Back to my question, I make my own frontend code to acquire data. I can create a 
midas file to store the bank. But I have no idea about reading the data from the 
midas file so that I can get my custom plots. Also, I would like to know how can 
I retrieve the online data from MIDAS so that I can create my custom online plots 
during the experiment. Thank you.

Best,
Terry
