New in Version 4.2.2
This release fixes the known issues reported in 4.2.1: the inability to read in project files due to the fixes (changes) in the NXcanSAS reader, and the fact that the 2D resolution was only being applied to one quadrant.
Fixes sasview # 1269: Problem reopening saved project .svs file
Fixes sasview # 1074: Resolution smearing is only applied to positive Qx and Qy in 2D
A problem has been identified in Version 4.2.2 which also affects versions 5.0.0 and 5.0.1. The Easy Sum|Multi Editor dialog should not be used to combine a plugin model with a built-in model, or to combine two plugin models. The operation will appear to work in 4.2.x but may generate a faulty plugin model. If it is necessary to generate a plugin model from more than two built-in models, please edit the plugin model .py file directly and specify the combination of built-in models directly. For example:
from sasmodels.core import load_model_info from sasmodels.sasview_model import make_model_from_info model_info = load_model_info('power_law + fractal + gaussian_peak + gaussian_peak') model_info.name = 'MyBigPluginModel' model_info.description = 'For fitting pores in crystalline framework' Model = make_model_from_info(model_info)
Moreover the issues with older plugins noted in 4.2.0 release notes remain valid.
