27/04/2016Submitteddmfit#20150521 Error Reading File
I am a new DMfit user. My problem is I can't open .asc files into DMfit. When I drag the file into the window, I just keep getting the error reading file message. I have tried exactly the same method on other computers and it works. Can somebody help me with this?

12/04/2016Submitteddmfit#20150521 how to optimize CQ and etaQ autumatically using Dmfit?
I have the same problem as that described by user 'umbingz1' on version dmfit#20111221. I have been trying to fit Qmas 1/2 to a B[3] peak, but even when I place the '*' next to the CQ and etaQ values in the model parameters box, it won't autometically refine those parameters.

11/04/2016Submitteddmfit#20150521 Incompatible values for Tools>Integrate and Model Integrate
It would be really cool if the integrated peak areas for modeled peaks had the same treatment of intensity as the values reported when using Tools > Integrate

11/04/2016Submitteddmfit#20150521 View window effects model integration.
On the 2015x64, 2015x32, 2011x64, and 2011x32 versions I have tested this on, the size of the view port effects the integration of modeled peaks. If zoomed in too close, it seems like modeled peaks outside the model are not counted in the integration. If zoomed out too far (especially a problem for spectra with very large sweep widths) the integration no longer becomes accurate to the actual modeled peak areas.

16/03/2016Submitteddmfit#20150521 nuQ/Cq mismatch
Using simple Czjzek fitting you can choose either quadrupolar product (nuQ) or quadrupolar constant (Cq) as a parameter. But when you switch the quadrupolar product is recalculated to Cq by multiplying nuQ by 6.66. Moreover the value is not correlated with data obtained from mqmas, i.e. when you estimate SOQE from mqmas and put it in nuQ you get a result very far from reality. Maybe be here is a problem with definition of nuQ (maybe nuQ is not quadrupolar product) since no exact equation is given on the website. Also the program crashes when you try to display all curves in simple Czjzek mode (if you have 2-3 or more lines and you put min CSA step to 5 or less).

10/03/2015Submitteddmfit#20111221 QCC fit error estimation
I'm fitting a series of deuterium quadrupolar MAS spectra and noticed some odd results regarding error estimation. The error of etaQ and lots of my fits have error that doesn't make sense. For example, the obtained error of etaQ is 0.50 while the obtained etaQ=0.08. This is a very large error (~600%) and will make the lower bound of etaQ to a negative value, -0.42 (the definition of etaQ suppose to be 0<=etaQ<=1). Is there any documentation describing the error estimation in DMFit. I do notice that in the optimization window of DMFit, it say 'Error estimation -under development May 2009'. Does this mean that the error estimation is not functioning now? Thank you!

18/12/2014Submitteddmfit#20111221 Negative fitting sum
Not sure if this is my operating fault, or a software bug: The sum of a fit yields a negativ value, but from visual inspection, the shapes don't add up to such a negative value. Also,

05/11/2014Submitteddmfit#20111221 Dmfit does not open bruker/varian fid files
I'm running dmfit on an OSX mac using wine. The program seems to work fine- I'm able to download and manipulate samples provided (YAG_for_TOP.fxmla) but cannot open any of my own bruker or varian files (fid). The program displays the message "a filename cannot contain any of the following characters: /:<>|". However, the files do not have any of those characters.

16/10/2014Submitteddmfit#20111221 how to optimize CQ and etaQ autumatically using Dmfit?
Hi there, I failed to autumatically optimize the QI parameters of CQ and etaQ except Amplitude and Postions, although I tried to add star at the right box of CQ and etaQ on "New Model Parameter full list" panel as User Guide suggested. It only can optimze the parameters of Amplitude and Position (in bold font) autumatically no matter for static or MAS spectra. So could you please help me by instructing me how to make Dmfit to simulate CQ and etaQ autumatically as it does to the parameters of Amplitude and Position? Many thanks! Bing

17/01/2012Submitteddmfit#20111221 the program still not works properly, I tried lots of different versions....
-crash whenever "new fit" is started or when starting from an old fit new data is loaded Solution: I installed a Windows XP emulation program from http://www.microsoft.com/windows/virtual-pc/download.aspx Although this is not a good solution, all versions of dmfit work now!

Hello, I run the program with Windows 7. Every time I want to start a "New fit" the program crashes. I would really like to use it, but it just won't work on my notebook.

27/06/2011Submitteddmfit#20110512 Miss-reporting of negative values of Gauss/Lorentz ratio after optimizing
When an negative value for the Gauss/Lorentz ratio is obtained after optimisation the parameters reported at the bottom of the screen and the parameter report shows 0.00. But the line of best fit still represents the solution for a negative value for x. (I know this because if the value of x is fixed at 0.00 and replot the curve looks different.)

The program crashes during opening of older Bruker Winfit examples like PPNA2S or GLYCINCP in Windows 7 Enterprise Edition x64 SP1
michael.fechtelkord This is true as the 64bits version cannot read older binary coded datafiles :
  • *.f01 parameters
  • Bruker binary coded parameters datafiles of pre 'J-Camp DX' versions etc…
Future versions will issue a warning at least…
