[Radiance-general] rcontrib: warning - partial accumulaton in final record

[Greg Ward]

Hi Germán,

As you can see, rcontrib is passed binary data from rfluxmtx (-fda), and we have seen issues with this on Windows in the past, but I've been told it's no longer a problem.  The best way to test is to temporarily replace the rcontrib command with something that captures the input to a file, so we can check that it's the right length.  In Unix, you would do this with an executable shell script like the following and call it "rcontrib":

:
cat > /tmp/saved_data.bin

On Windows, you might need to write a Perl program.  Just make sure it's something that correctly captures binary data without doing anything to it.  Then, make sure the file contains 145*10000*6*8 bytes in it.

-Greg
