Hi,
 
I must admit I am rather new to wireshark, thus I just used the export function of wireshark to export (producing a cvs file) the data, which made it a rather difficult job to process the exported file. Matlab lets you read numerical data from an ascii file into a matrix, where rows are separated by \n and columns by a white space. Thus to process TCP data it would be helpful to be able sperate the values contained within the info/summary-field into different columns, e.g. source port, desination port, window size, length, ACK-number, Flags, RTT (which I think is not possible on a per packet base).
 
Cheers,
