I've done some more tests on the lowess problem. Please refer from now on to our development server:
http://base.vectorbase.org:8080/base2dev/ Experiment: "Male vs. female (Koutsos et al., 2007)" I ran the base1 lowess plugin and got a very different result compared to the base2 plugin. The base1 plugin results look correct to me. The base2 correction factor plots do not look at all right to me. Can anyone hazard a guess as to if this is a bug or are the default parameters not suitable for my data? Due to time pressures I think I'm going to have to switch all our analysis over to use the base1 plugin. many thanks, Bob.
