Hi Stuart, Jan
<div class=""><br class="">
</div>
<div class="">The data Stuart has is NOT legacy and the format he was using was correct. Clearly directory2filelist does not support VDIF for some reason. Given I assume it uses mark5access under the hood, that surprises me.</div>

due to the strange VDIF format error you could use DiFX utility "printVDIFheader" to verify what the headers of vygr2_wa_no0108 actually say.<o:p class=""></o:p></div>

In that case the frame header size would then be 16 instead of 32 bytes, and format VDIFL instead of VDIF, with a format string *possibly* of "VDIFL_8000-128-2-2". Which in v2d would translate to "format=VDIFL/8016/2".<o:p class=""></o:p></div>

And as Simone already pointed out, "vsum -s <vdif files>" could be a more convenient way of generating a file list for a set of VDIF files. Vsum autodetects the nasty details of the VDIF format.<o:p class=""></o:p></div>

Also for v2d ephemFile has to be either tle (Two-Line elements) or bsp (which I assume means BaryCenter on 399 Earth, our observing platform). Now NASA HORIZONS doesn’t seem to produce a valid file acceptable to SPICE. So goto NASA NAIF which has some “old”

Note: Future versions of vex2difx may stop allowing file lists without start/stop times. Filelists for VDIF and Mark5B files with start/stop times can be generated with "vsum -s" and "m5bsum -s" respectively. These times allow vex2difx to properly assign
data to jobs and is especially important in cases where multiple jobs are generated per project.<o:p class=""></o:p></div>
