psi.plotMultiplePMFs ( B0, B1, B2, ci=True ) broken

2011-11-30T10:20:48Z

When I run the example given in the docstring of plotMultiplePMFs(), but add a parameter 'ci=True' I get an exception:

/usr/lib/pymodules/python2.6/pypsignifit/psignidata.pyc in getCI(self, cut, conf, thres_or_slope)
423
424 if thres_or_slope[0] == "t":
--> 425 bias = self.__th_bias[cut]
426 acc = self.__th_acc[cut]
427

TypeError: 'NoneType' object is unsubscriptable

MapEstimate error

Just downloaded psignifit for Matlab (I'm using a PC),
here is the error I get when I try to run the test_psignifit:

>> test_psignifit
testing 2afc setting
MapEstimate
Error using MapEstimate (line 156)
Error: Unexpected MATLAB expression.

Error in test_psignifit (line 9)
mapest = MapEstimate ( data2afc, priors );

Evaluating the psychometric function of a BootstrapInference object "B" at a given stimulus intensity x using B.evaluate(x) results in the following error message:

>>> B.evaluate(3.3)

import error due to wrong lib path under ubuntu 9.10

2010-03-10T16:07:34Z

After installing psignifit under ubuntu 9.10 I get the following error when I try to import psignifit in python:

>>> import psignifit
ImportError: No module named _psipy

Python can't find the _psipy.so library file, probably because it is located in a wrong path (/usr/local/lib/python2.6/dist-packages)

A workaround is to install signifit for the current user only:
python setup.py install --home=~

this makes python copy the _psipy.so in the home directory's lib folder (/home/USER/lib/python/).
Add this path to the PYTHONPATH to be able to import psignifit in python:
export PYTHONPATH=$HOME/lib/python/
