Hello Charles ...

Thanks for the fix on pdbLoad...

I have been using the solution scattering potl. (following the examples on
the help pages). Without  the solution scattering term all work well.
Whenever I use the solnScattering I get the following error:
"SystemError: xplor-nih error: only derivatives of uniform calcType are
supported".  The protein is highly flexible and SAXS data has no significant
secondary structural details.  (e.g part of the code at the end).

If I am justified to use such a SAXS profile? If 'yes' is there a fix?

with best

from solnXRayPotTools import create_solnXRayPot
xray61 = create_solnXRayPot('xray61',experiment="c1.dat")
xray61.setNormalizeIndex(0)
xray30 = create_solnXRayPot('xray30',experiment="c1.dat")
xray30.setNormalizeIndex(0)
xray      = xray30xrayCross = xray61
solnXRayPotTools.useGlobs(xray)
xray.setNumAngles(100)
xrayCross.setCalcType('n2')
xray.setScale(4000)
potList.append(xray)
