I'm not sure if I'm on the right track here, but if you're saving the file through LV, then a look at the code should reveal everything you need to know about the file. The easiest thing may be to write a VI to convert the data into a more Matlab-compatible format. This requires also that you already know the format of the file, in which case the problem is already solved. Ah Catch 22.....
Otherwise, if a *.bin is a standard filetype I have no experience with is, sorry. Shane.
