Klustaviewa error on loading example file

[grg2rsr]

I ran the example file from the example data repository that is linked on the readme of klusta-team/example. After getting it only to run with a different parameter file (not the one that is in the .zip), I can't open the resulting .kwik file in klustaviewa.

Running linux mint 17.

Hi, I had the same problem, turned out to be due to python dependiencies - pandas=0.12 and pytables=3.0.0. However, it does not run clean even though it works - i'll make a new issue on this.

[grg2rsr]

I have

Name: pandas Version: 0.16.0

and I installed it via the standard ubuntu repositories. So if pandas broke downward compatibility somewhere between 0.12 and 0.16, a lot of people should suffer from this, or not?

[rossant]

yes pandas 0.12 is required (see https://github.com/klusta-team/example/blob/master/install.md#dependencies)

the new version of klustaviewa (phy) does not depend on pandas anymore
