Opening SigmaPlot files (.jnb)
Hi all,
In the past we've discussed at length various different packages with which to
plot data for publication. As a result of such discussions, I even ended up
maintaining a couple of these packages in Debian...
This time, I'm not looking for alternatives for plotting things but for a way
of opening SigmaPlot files. I'm in the classic non-free software trap where
I've been suckered in and am now trapped [1]:
* I have with a set of data files that students and colleagues have prepared
for me
* They used the software that was preinstalled on their department-issued
machines, meaning that I have lots of files in SigmaPlot as that was site-
licensed at the time.
* As soon as the site licence is no longer available (because you no longer
renew it or because you no longer work at that institution), you can't use
SigmaPlot.
So... do we have any utility (in Debian or more widely in the free software
ecosystem) that can open these .jnb files from SigmaPlot [2]? The ideal
situation would be where I can import the entire notebook (data, calculated
sets and then plots) into something [3], but would be happy to accept just
being able to extract the data as columns in order to be able to plot it again
using my graphics utility of choice.
thanks in advance
Stuart
[1] Yes this is *exactly* the classic non-free software trap. You'd think I'd
know better than to end up here...
[2] JNB files are a notebook format of some description that contains "sheets"
of data and "pages" of plots. The file format change incompatibly at SigmaPlot
version 9ish (iirc); I have the newer format files. Magic information isn't
very useful.
$ file -k redacted.JNB
redacted.JNB: Composite Document File V2 Document, Little Endian, Os 0,
Version: 5.1, Title: Notebook, corrupt: Can't expand summary_info
[3] I know packages like scidavis/qtiplot can open origin project files like
this.
