[...] failed replication, as shown by the Ababneh Thesis. Not only that, but one of the authors of M2008 (Malcolm Hughes) had to have known that, because he was on her PhD committee … so the M2008 study used [...]

Re: RomanM (#85), Found the glitch in mwa_rwl. It wasn't in my R script. There are two consecutive cores labelled MWA069x in the file. They start in the same year, but consist of two different sequences of ring widths and end at different times.

Supporting data has been placed online in commendable fashion. I'm working on an analysis

See? Anyone can do it!

Re: RomanM (#84), I got my script working. There is a small glitch with mwa_rwl, and only in one spot I haven't identified yet. My method uses readLines and then I parse the lines to extract the data. It is quite fast in its execution.

Steve: Supporting data has been placed online in commendable fashion. I'm working on an analysis.

I have been trying to read the tree ring files using both your progamme (make.rwl) and the dplR library with hiccups in both methods on some of the rwl files. I am writing up my own script. I also noticed a lack of uniformity in the files with regard to end-of-data values and number of digits in the values. Are there soem glitches in the files as well or is it just me? Steve: Roman, I'll post up collations in 2 minutes to save you time on clerical work. I had to do a couple of tweaks to make.rwl. You need to use the widths option widths=c(7,5,rep(6,10)). Also I had to specify the first item as a factor using colClasses. Ill also upload modified make.rwl in two minutes. QCed collations in my usual style will be in CA/data/salzer.

Re: Steve McIntyre (#81), Any sign of any supporting data? Or is Hughes still working on them? Steve: Supporting data has been placed online in commendable fashion. I'm working on an analysis.

Re: Pat Frank (#40), The Pat Frank on comment 40ff isn't the one -- me -- who has been posting for years here on sundry threads about AGW and tree ring thermometry, works at Stanford, and wrote the Skeptic article. [Jean S: Are you sure about that? #40 has the same originating IP as this one, and the e-mail address seems to be the Standford address you used to give at that time.]

ping – the new Salzer, Hughes paper appears to be a writeup of Hughes’ 2007 AGU presentation.

I’ve also received some correspondence in the past year from a scientist who knows Linah Ababneh and vouches for her in very positive terms.

Re: bender (#79), metadata - you kidding me??? For example, the Avam-Taymyr metadata doesn't even show which site a sample is from - and the sites are 400 km apart. I've started a new Yamal thread.

Steve, are there enough samples in the raw Yamal data, and enough metadata – to check if the slope of the uptick varies according to aspect? I bet the metadata don’t even include aspect. But depending on the precision on that lat/lons, you could look it up from a digital elevation model.
