Category: Applet Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: molvisions (molvisions) Assigned to: Bob Hanson (hansonr) Summary: weird color application Initial Comment: hi, this is a difficult bug to file because I can't pin down exactly when it happens (it seems random at the moment). I am loading an external file with values, and coloring atoms according to those values. a demo can be seen here: <http://www.molvisions.com/impas/> or, since my server is wicked slow, downloaded from here: <http://www.molvisions.com/impas/gly_bact_min.tar> basically, I load the external file and then use blocks of select statements to color atoms; for example: select backbone1 and (property_potc1 > 1 and property_potc1 < 3) color atoms yellow color atoms translucent 0.9 clicking a radio button in the above demo should apply a single coloring script of this form. but, even though the script and data for each button are exactly the same, often the resulting color scheme is very different. for example, sometimes I see a nice, and extremely wrong, rainbow gradient in the right-hand structure. but not always. I hope that description made sense. can anyone see a reason why this might be happening? thanks, tim driscoll ---------------------------------------------------------------------- >Comment By: Bob Hanson (hansonr) Date: 2007-11-10 17:40 Message: Logged In: YES user_id=1082841 Originator: NO Now that I have Jmol 11.3.43 running with your page, Tim, I see that: 1) The images you saw initially with the radio buttons were correct. 2) Jmol 11.3.42 has a bug that prevents using propertyAtomNumberField anyway. 3) Jmol 11.3.43 shows the same colors, but is doing the mapping correctly, so it is independent of the selected atom set. 4) The key to always getting the same picture with the earlier version of Jmol, since you are NOT using propertyAtomNumberField, is to add select * just before the data statement. I'm guessing that without the atom number field sometimes you had a different selection, and in that case, since the selection is used, it would totally mess up the colors.

Mostly I think the problem was that you used "propertyAtomField" instead of "propertyAtomNumberFeld", and that resulted in the data being misread. I think our new recommendation to use "SET" for Jmol parameters will pay off in this regard. I noticed it because the variable was listed in the state under "user-defined variables" instead of Jmol parameters. Clearly we need some more feedback in those data statements that allow you to check that data were read properly. Aside from that, I recommend using "var" with your variables. This confines them to the script being run, and when that finishes, then they are flushed, saving memory on those huge data lists. Looks like it will be a fabulous resource.

No sense talking about bugs in 11.1.37. Comments: color atoms [75,75,75] color atoms translucent 0.9 color trace [75,75,75] select backbone1 and (property_potc1 > 0 and property_potc1 < 2) 1. You can do this and save one step: color atoms translucent 0.9 [75,75,75] 2. OK, you've got me. Why not just select backbone1 and (property_potc1 = 1) 3. With Jmol 11.4.43 you can instead make an array of your color list and process it like this: mycolors = "[xff0000],[xff2200],[xff2244],[xff44ff]".split(","); for (var i = 1; i <= mycolors.size; i = i + 1); print " " + i + " color= " + mycolors[i] + " " + mycolors[i].color; select backbone1 and property_potc1 = i; color atoms translucent 0.9 @{mycolors[i]}; color trace @{mycolors[i]}; end for; ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379133&aid=1829276&group_id=23629 ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
