New free software tool for impedance fitting and plotting

[Søren Koch]

The department of Energy Conversion and Storage at the Danish Technical University have released a new open source software tool for fitting impedance spectra.

Elchemea Analytical can be downloaded for free from http://www.elchemea.com or tried out directly on the download server.

I hope that you will try it out and if you find any problems or errors, to contact us so that we can get them fixed.

Elchemea Analytical is distributed under the GPL, so feel free to distribute :-)

If you have any questions, post them here or send me an email.

Yours
Søren Koch, Lead developer.

Hi,

  This software cannot be installed with windows xp 64 bit or can because in specification only Linux is mentioned. Can you please guide me.

Thanks,

Well, it is developed to run under CentOS, so if you could install CentOS in a virtual machine in principle it should work if you then install it there, however We have not tried that.

As of now we have no plans to port it to run natively under Windows, however it is distributed under the GPL, so if someone wants to port it, they are free to do so (considering the normal copyright clauses in the GPL).

PS: Merry Christmas!

Oh Ok.

Thanks,

Søren,

could you elaborate what numerical engine is used for the complex spectra fitting?

Is it based on some method that is described in some publications? If so, could you point to

it, or just describe the method in a few words?

Regards,
Yevgen

Elchema Analytical uses Gnuplot for the actual math/fitting and Gnuplot uses non linear least square regression for fitting. For the actual nut's and bolt's about that, you would have to consult Gnuplot's manual (gnuplot.org).

Hi Khoncj.

Thanks for trying our software. I'm sorry that you have encountered
problems with the installation and I will try to help.

Do you intend to install a full version (including web service support),
in that case we have not tried that under Ubuntu, there we have only
tested command line only installation (make install_cmdonly / sudo make
install_cmdonly).

I am not sure that a full installation is possible in Ubuntu as it does
not normally include a web server (apache)
I think what is the problem is that make can not find the web directory
(usually /var/www/cgi-bin/) and thus tries to create the analytic
directory in / (which of cause is forbidden)

Try to run make install_cmdonly and see if that can install correctly,
if you then later want to upgrade to a full wersion you can always run
make install on top...

I hope that you can get it to work 

Yours

I have just been aware that gnuplot.org is no longer the correct link for the gnuplot manuals etc. now it is http://www.gnuplot.info/
