[Chimera-users] Integer Values instead of Floats in Render by Attribute

Hi Daniil,
I cannot reproduce this problem on my Mac using your exact attribute file with pdb 1gc1 (which has an L chain), and either today’s daily build or the 1.13 release.  I can move the slider continuously so that the Value field in Render by Attribute shows float values, and type in any float value as well.  I also tried it with a similar attribute file where I added more residues just so it was easier to see values on the histogram.

Maybe it is something platform-specific.  I recommend using menu: Help… Report a Bug (which will include info about the platform), say which PDB file you are using and attach an attribute assignment file that exhibits the problem.  (and include your e-mail address if you want feedback on the bug report)

This does not happen with "native" attributes, only with the newly defined one. Is it a problem with the defattr function not determining/passing the data type correctly? I am pasting the top of the attribute deffinition file below.
