[Homer-users] HOMER issues with PMI toolbox 1.0

[Maria Angela Franceschini]

Hi Ted,
the error bars in the new version of homer (standard errors and standard
deviations) are much bigger than the ones of version 3. Like 10 times bigger
or more.
which ones are the correct ones?

please let me know

mari
