Re: [Ifeffit] The road to Athena... (and Artemis too!)

The fact that the wrapper for python worked as it was occurred to me after I hit the send button. How does the loader work on BSD? Does it expect libraries to be in certain standard places? Perhaps Chuck ended up with the ifeffit library in some non-standard place and so needs to fix that, set an environment variable (like on SGI), or fix the loader configuration (like on linux). Anyway, I am glad to hear that such good progress is being made. I wish I could contribute more to the immediate problem. Do post the screen messages from the build, as Matt suggested. I mostly grok perl's strange and numerous messages (which must say something bad about me .... ;-) I wanted to mention that this week I made some good progress on Artemis (I had all of Monday at home watching a contractor poke holes in my walls!) There are still alot of clunky interface problems, but Artemis will run to completion a fit with one data set using any number of feff calculations and it will plot the results in a manner that rsembles Athena. That is, you can select the data, the fit, and/or any number of paths from the list in the skinny panel on the right and click a button for plotting in k, R, or q. Model building needs a lot of work, but its usable. I would love if the Mac effort could succeed soon -- that would somewhat increase the number of alpha testers ;-) B -- Bruce Ravel ----------------------------------- ravel(a)phys.washington.edu U.S. Naval Research Laboratory, Code 6134 phone: (1) 202 767 5947 Washington DC 20375, USA fax: (1) 202 767 1697 NRL Synchrotron Radiation Consortium (NRL-SRC) Beamlines X11a, X11b, X23b, X24c, U4b National Synchrotron Light Source Brookhaven National Laboratory, Upton, NY 11973 My homepage: http://feff.phys.washington.edu/~ravel EXAFS software: http://feff.phys.washington.edu/~ravel/software/exafs/

The road to Athena...
by Charles Bouldin 07 Mar '02

Bruce sez to try this to test if things are in place for Athena: >#!/usr/bin/perl -w >use Tk; >use Ifeffit qw(get_scalar); >use Tk::Dialog; >my $x = get_scalar('etok'); >my $top=MainWindow->new(); >$top->Label(-text=>"Ifeffit sez etok=$x") ->pack(); >$top->Button(-text=>'Done', -command=>sub{exit})->pack(); >MainLoop; I tried it and got: >[h196132:~/Desktop] charlesb% perl test_ifeffit.pl >Can't locate Ifeffit.pm in @INC (@INC contains: /sw/lib/perl5/darwin >/sw/lib/perl5 /System/Library/Pe >rl/darwin /System/Library/Perl /Library/Perl/darwin /Library/Perl >/Library/Perl /Network/Library/Perl >/darwin /Network/Library/Perl /Network/Library/Perl .) at >test_ifeffit.pl line 3. >BEGIN failed--compilation aborted at test_ifeffit.pl line 3. But then I realized I needed to At 12:01 PM -0600 3/7/02, ifeffit-request(a)millenia.cars.aps.anl.gov wrote: > cd ../../wrappers/perl > perl Makefile.PL > sudo make install So, I did that, but now I get >[h196132:~/Desktop] charlesb% perl test_ifeffit.pl >dyld: perl Undefined symbols: >_ifeffit_ >_iff_exec >_iff_get_array >_iff_get_echo >_iff_get_scalar >_iff_get_string >_iff_put_array >_iff_put_scalar >_iff_put_string >_iffgetarr_ >_iffgetecho_ >_iffgetsca_ >_iffgetstr_ >_iffputarr_ and I'm not sure why this is happening. However, this feels close to working. More suggestions?

How to run ifeffit from terminal.app
by Charles Bouldin 07 Mar '02

07 Mar '02

Thanks to helpful folks on usenet, who seem amused that Maccies are starting to ask such basic questions, here is how to run ifeffit from terminal.app: >: Wow, this sounds close to a solution to something I've been puzzling >: over. I have Xwindows installed and I can use pgplot from an xterm >: running under XDarwin, but I can NOT run pgplot from Terminal.app. If I >: try I get a message: >: PGPLOT /xw: cannot connect to X server >: I tried putting the DISPLAY=:0.0 export DISPLAY into .xinitrc and >: .cshrc, to no avail. Basically, I don't know what I'm doing here :) and >: I am just blundering about. > >That command is for sh/bash, not tcsh. For tcsh, you want > setenv DISPLAY :0.0 > >If you're going to put it in your .cshrc file, then use > if( ! $?DISPLAY ) setenv DISPLAY :0.0 >so it won't override DISPLAY if it's already set, such as by >a forwarded X11 connection. There were several interesting replies, one of which was basically, "I know how to fix it, but I refuse to use c shells". What's -that- about?

Status of ifeffit, atoms, athena, etc on MacOS X
by Charles Bouldin 06 Mar '02

06 Mar '02

This may be the first message on the mailing list? It is a message mostly composed of questions: I have ifeffit and atoms running just fine on MacOS X, thanks to Francois' hard work figuring some things out and Matt's quick port of ifeffit. 1. Does anyone have Athena running? 2. Is anyone able to run ifeffit from Terminal.app, as opposed to running it from an xterm? When I try this, I get an error message, "PGPLOT /xw: cannot connect to X server". When I do ps -aux | grep pgp I see a process charlesb 3239 0.0 0.1 67316 672 std- S 0:00.04 /sw/pgplot/pgxwin_server -display :0.0 so clearly I need to something to tell terminal.app about the pgplot server? Anyone have advice on this? I just don't know where to look beyond this point. Why do I care about this distinction? (1) Terminal.app supports cut/copy/paste, (2) terminal.app is scriptable, which means that you can define define macros, or use script menu to put in common command blocks. In principle, this means that you could use Applescript studio to control ifeffit from a mac-native gui. 3. Has anyone run ifeffit using aquaterm? I'm very heartened by the recent rapid progress and hope that it can continue.

Ifeffit Mailing List

OK, after two short weeks waiting for the APS firewall to allow the mail server to work, it appears that the Ifeffit mailing list is now really open for business! You can join this list or read the archives from http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit/ Thanks, --Matt |= Matthew Newville mailto:newville@cars.uchicago.edu |= GSECARS, Bldg 434A voice: (630) 252-0431 / 1713 |= Argonne Natl Lab fax: (630) 252-0443 |= 9700 South Cass Ave http://cars9.uchicago.edu/~newville/ |= Argonne, IL 60439 USA

Ifeffit Mailing List
by Matt Newville 21 Feb '02

21 Feb '02

Dear Friends of Ifeffit, Over the past few weeks there has been quite a bit of email flying back and forth about Ifeffit and a variety of related subjects: building on MacOS X, installations scripts for Win32, phase-corrected FTs, Tables for Feff calculations, and a bug report or two. It's been quite a challenge for me to keep up with it all! At Bruce's suggestion, and in an effort to cut down on the amount of repeated and partial information, I set up a mailing list for Ifeffit. You can join this list or simply read the archives. You do not have to join the list to post a message. To join the list or browse the (currently very short!) archive, go to http://cars9.uchicago.edu/mailman/listinfo/ifeffit/ Of course, you can still send me mail about Ifeffit, but please consider using this list for Ifeffit-related mail. Since these messages will be put in a public archive, anyone with similar questions, or answers, will be able to see the messages. Thanks, --Matt |= Matthew Newville mailto:newville@cars.uchicago.edu |= GSECARS, Bldg 434A voice: (630) 252-0431 / 1713 |= Argonne Natl Lab fax: (630) 252-0443 |= 9700 South Cass Ave http://cars9.uchicago.edu/~newville/ |= Argonne, IL 60439 USA

Welcome!
by Matt Newville 20 Feb '02

Dear Friends, Welcome to the Ifeffit Mailing list. This list is intened for announcements, questions, and discussion of Ifeffit and related programs (including, but not limited to Feffit, Autobk, Atoms, G.I.Feffit, Athena, and Diffkk). It is also intended for discussion of the Analysis of XAFS and related spectroscopies. Although there is a separate mailing list for Feff Users and Development (see http://leonardo.phys.washington.edu/feff) questions and discussion of how Feff relates to XAFS Analysis, and the use of Feff calculations in XAFS Analysis are welcome here too. Thanks, --Matt Newville |= Matthew Newville mailto:newville@cars.uchicago.edu |= GSECARS, Bldg 434A voice: (630) 252-0431 / 1713 |= Argonne Natl Lab fax: (630) 252-0443 |= 9700 South Cass Ave http://cars9.uchicago.edu/~newville/ |= Argonne, IL 60439 USA
