To Wayne Rasband: NIH ImageJ question regarding SKEW
Hi Wayne:
I am an emeritus professor at URI who uses NIH Image J to measure cardiac
and skeletal muscle mitochondria. I neglected to add the SKEW measurement
of mitochondrial area and Feret in my assessment of over 10,000 myocardial
mitochondria in a drug treated and exercise intervention study so I
measured SKEW from the "Results .xls data. Our statistician found that
exercise and PPARy had not treatment effects. He stated the following:
However, I’m not sure that it is equivalent to how the NIH software is
calculating the third order spatial moment mean in regards to pixels for
individual mitochondria rather than the skewness of a distribution of many
mitochondria in a given micrograph. If you believe the distributional
skewness from excel is correct then the results are below however, if not,
then you’ll need to use the NIH software to calculate it to be sure we are
aligned with what Pickard has done.
I agree with him that we need an answer to this question. Also, can I
recapture the ImageJ files prior to the .xls files and put SKEW into the
menu?
Thank you Wayne. Your software is indeed an excellent tool in our research.
Regards,
Tom
