As such, the endianness is thankfully irrelevant. I know the data array will have a shape (/448, 304/), but it is stored after a header that is 300 bytes long. After reading through the binary guidance and hints (<a href="https://www.ncl.ucar.edu/Applications/r-binary.shtml">https://www.ncl.ucar.edu/Applications/r-binary.shtml</a>), I’ve been unsuccessful in getting started. For some other languages I’ve used, there is a ‘skip bytes’ flag that can be added to read functions to make this process a bit simpler. I thought that was where the “rec_num” came in for fbindirread, fbinrecread, and craybinrecread. I.e. rec_num = 299 would then allow the function to start reading at location 300, byte 301? </div><div><br></div><div>The data file I’m trying to read is attached to this message.
