Hi,
I'm trying to read in a data from a binary-formatted file. I have the data format, (available at: http://www1.ncdc.noaa.gov/pub/data/documentlibrary/tddoc/td7000.pdf if you're really curious), but it's not what I would consider simple, with a lot of different blocks and messages, some that are optional and some that have different formats depending on the data type. My question is, has anyone dealt with data like this using numpy? Have you found a good pattern for how to construct a numpy dtype dynamically to decode the different parts of the file appropriately as you go along?
Any insight would be appreciated.

Ryan, http://currents.soest.hawaii.edu/hg/hgwebdir.cgi/pycurrents/file/d7c5c9aac32... This gives an example of reading several related and rather complex binary file types generated by (oceanographic) acoustic Doppler current profilers. I have not looked at the format you are dealing with, so I don't know if the methods I used are applicable to your case. Eric
