Try this:<div class=""><br class=""></div><div class="">L = ds.arr([-1, 1, 0], 'code_length') # this explicltly sets the projection vector to be in code length instead of unitary</div></div></blockquote></div><div class=""><div dir="ltr" class=""><div class=""><br class=""></div></div></div><div class="">I’m not sure about this. This may work, but I think this is a bug on our end—the projection vector shouldn’t have units. I also don’t know why it’s failing in this way on this dataset and not others. It may have to do with the fact that the dataset is non-cubical. </div><div class=""><br class=""></div><div class="">Jeff, is there any chance you can post the dataset somewhere (like Dropbox or Google Drive or something), so that one of us can debug it in more detail? You can send email to <a href="mailto:jzuhone@gmail.com" class="">jzuhone@gmail.com</a> with the location of the dataset if you don’t want everyone to have it. </div><div class=""><br class=""></div><div class="">Best,</div><div class=""><br class=""></div><div class="">John Z</div><div class=""><br class=""></div></body></html>
