17 Sep 2011	Mia 2.4 Medical Image Analysis GUI. Author: Laszlo Balkay	I have corrected the link of the documentation
08 Sep 2011	2D Histogram Calculation Quick computation of two-dimensional histogram of bivariate data Author: Laszlo Balkay	Comment to John: You should not transpose the histmat matrix: The pcolor(xedges,yedges,histmat) will work.
31 Jan 2011	Mia 2.4 Medical Image Analysis GUI. Author: Laszlo Balkay	Comment to Yawar Rehman: Sorry, I was just reading your questions. I wrote a new function to read the mnc format files based on the NETCDF bultin matlab library. If you intrested in I will send you (balkay@pet.dote.hu)
15 Jul 2009	Mia 2.4 Medical Image Analysis GUI. Author: Laszlo Balkay	Comment to Kiran: I never try 3D US data. Is this a dicom format?
14 Feb 2009	roitool Interactive roi definition tool Author: Laszlo Balkay	Comment to Winnie: You can get the ROI handler issuing (for example) ">> roi_handler = roitool('circledemo');" and the ROI coordinates can be import by "x = get(roi_handler,'Xdata'); y = get(roi_handler,'Ydata');"

06 Feb 2012	2D Histogram Calculation Quick computation of two-dimensional histogram of bivariate data Author: Laszlo Balkay	Alwan	Hi. How can I get the actual data points instead of its index. I actually want to add the magnitudes of the data that fall in each bin. Thank you
22 Jan 2012	Mia 2.4 Medical Image Analysis GUI. Author: Laszlo Balkay	Vino	Hi Laszlo, I have some problem in opening the DICOM images or DICOMDIR....I am getting the following error Error using ==> images\private\dicom_set_mmeta_encoding. Invalid transfer syntax UID "1.2.840.10008.1.2.4.91" What this error mean..? can u plz help... Thanks a lot
30 Dec 2011	FCS data reader Read FCS 2.0 and FCS 3.0 format flow cytometry files Author: Laszlo Balkay	McFarland, Malcolm	I was initially unable to get this code to read BD Influx FCS files created with Sortware software. I found that the mnemonic_separator is 'LF' (line feed) and the data precision is 'uint16'. I modified the get_mnemonic_value subfunction and the section that reads events. It now works well, although I think some header information is missing. Thanks for some very helpful code.

01 Sep 2011	2D Histogram Calculation Quick computation of two-dimensional histogram of bivariate data	John	I'm having trouble with this routine. In the example below, the x and y ranges dont' seem to be correct, and also the distribution doesn't look right either. function hist3_test close all; clc; events = 1000000; xrange=0:.1:1; nxs=length(xrange); x=[]; y=[]; for xx=0:.1:1 xs=xx+sqrt(0.005)randn(round(events/nxs),1); if (xx<.3) ys=cos(xs)+ sqrt(0.001)randn(round(events/nxs),1); else ys=cos(xs)+ sqrt(0.1)*randn(round(events/nxs),1); end x = [x; xs]; y = [y; ys]; end % For linearly spaced edges: figure; subplot(2,1,1); plot(x,y,'.'); xedges = linspace(-1,1,64); yedges = linspace(-1,1,64); histmat = hist2(x, y, xedges, yedges); subplot(2,1,2); % pcolor(xedges,yedges,histmat'); colorbar ; axis square tight ; izero = histmat==0; histmat(izero) = nan; h=pcolor(xedges,yedges,histmat'); colorbar ; axis square tight ; set(h,'edgecolor','none'); end	Comment only
