Dear Laura, have you consulted the helpful maual ? See pp 5-12 for mesor, acrophase etc. Its available on: http://www.chronopharmacology.de/software/Chronos-fit%20manual.pdf

Hi, please find an attachment for my group analysis manual. At first, you need to create an original chronos fit file (.aft) for each animal separately (for example from txt file - but I think that this is done). Then you can perform the group analysis in order with the manual. Good luck!

Thanks, Avijit and Lubos!

It was not clear to me that each animal has to be analyzed separately. I'm gonna report about my success later, hopefully ;)

Thanks for pointing me to the Chronos software. Great tool. You might also find some of the free software from the Hut Lab in Groningen useful (http://www.hutlab.nl/) - check under downloads. I specifically find ChronoShop by Kamiel Spoelstra very useful.

Best, Tom

Thanks, Tom! Great suggestion!

here we go...

I analyzed my data, receiving a similar output as Lubos (see the file I have attached, graph on the left side). Now I have a follow-up question.

In the manual, the authors display a graph under group analysis and comparison (see the file I have attached, graph on the right side), where they show a comparison of two groups over a period of about three days.

Does anyone know, how this was done?

I get a graph with one group only and it displays only 24 h.

Laura

Congratulation Laura :)

First - graph extension from 24 to 48 h: 'group analysis > options > graph options # end of x-axis (h)' - rewrite 24 to 48. 'OK' and 'recalculation'. Now, you can observe a double plot.

Second - two different groups in one graph. I have no idea as it is possible in Chronos-fit (I don't use this extension), but I think that you can use some graphic software (photoshop, gimp etc.). In Chronos-fit creat a graph for everyone group separately (with the same axis and another properties but with different colour) and then merge two output images into one in a graphic software.

Lubos

Man, thanks for the quick answer!

The authors say they did the graph with powerpoint, but first I have no clue how to do it there and second, you loose so much quality, when importing into and exporting from powerpoint, I guess.

I will give it a try with Photoshop first, if it doesn't work, there might be a nice graphing tool for R, I could install.

I will post my news ;)

Hi guys,

How did you get the registration file? I installed ChronosFit about a month ago and send the autors my details several times but did not get my registration file - so I had to uninstall as the program would not start without the file...

Hi Tom,

I have obtained the registration file 10 days later after emailing (support(at)chronopharmacology.de).

Greetings, Lubos

Hi Tom,

I don't remember exactly, but it was probably between one and two weeks after registration. Seems strange to me that it takes so long. Maybe you are successful, if you contact the Prof. directly: [email protected]

Cheers, Laura

Vielen Dank Laura,

Hi Anna,

information about registration of chronos-fit software are on the bottom of the page: http://www.chronopharmacology.de/software.htm

"We would like to keep track of people using the program. Therefore a free registration of Chronos-Fit is mandatory. In order to register the program send an e-mail with your name, company, city, country and e-mail adress to [email protected]. You will receive an e-mail with the file 'abpm.cfg' attached. Copy this file to the installation directory of Chronos-Fit (e.g. 'C:\Programs\Chronos-Fit'). Chronos-Fit will start without reminding you to registrate the software."

Greetings, Lubos

I have the same problem with mail delivery to [email protected] !

 Hi there :) I have similar problem I used chronosfit to convert my patients to .Aft form and I would like to perform group analysis in Chronosfit but there is some mistake and I really do not know how to solve it. I am sending picture under this.
