Hi, Can you please help me? Whenever I try to run f.ica.fmri.gui(), R crashes. In the GUI, I selected an *.img file and I checked the 'Create mask' box and I typed a name for the object and then I press 'Start' button. Then in the R Console window it said 'Reading...Whitening', but after the Whitening message an error window popped u...

...sers I have a two-dimensional array, whose values I want to plot, using the pixmapGrey class. Plotting works fine, and now I would like to be able to identify some of the points in the plot using identify(). But I get the following message while pressing the left mouse button: > plot(pixmapGrey(fmri.vtc[,,slice,volume])) > identify(fmri.vtc[,,slice,volume]) warning: no point with 0.25 inches pressing the right mouse button I get: numeric(0) what is the problem here and how can I solve it? many thanks for your help Cheers!

Hi all, I have a set of 3D statistical parametric maps derived from an fMRI experiment in which we have two levels of dependency. - All subjects were scanned twice. - All subject are dizygotic (non-identical) twins. For every single scan (and thus statical map) we have a behavioural measure, which we would like to regress against the set of maps, while correcting for the...

Hi all, I've noticed that many computational neuroscience research groups use MATLAB. While it's possible that MATLAB may have some features unavailable in R, I suspect that this may instead simply be a case of costly tradition, where researchers were taught MATLAB as students and pay for it as researchers because it's all they know. I'd like to attempt to break the cycle by

First time user, so sorry if I don't understand protocol.. Anyway, I have created a data frame consisting of pearson's R values at various x and y coordinates and then plotted this using filled.contour. My data is similar to fMRI data except that it is a surface map reconstructed from histological sections. I like the results but would like to know how contours were detected. Google search provides me various sources claiming the algorithm used is undocumented. For example: http://wipaed.wiso.uni-goettingen.de/~holdenb1/R...

...ion about the Package DierckxSpline. I have tried to find the answer by myself but it didn't worked out. I wondered if Dierckxspline can use different sets of y values in one time to fit a line with knot. I have different sets of Y values representing the same thing for different voxels (in an fmri image). I have already fitted the data in different graphs and I know now that the plots are comparable for the different data sets (so for the different voxels) but I wanted to include all the information in one plot, If it's possible. So I want to know the best fitting line for the whole clus...

...no reason to run as a domain 0 without making use of the control tools. All the services are standard contract services. 3. Xen Store Daemon /usr/lib/xenstored is a simple daemon implementing the database of configuration parameters for each virtual instance running, and has the FMRI: svc:/system/xctl/store:default. Due to significant Xen shortcomings, the daemon is not currently safely restartable; if it fails or is otherwise stopped, the Xen control tools as administered via xm will not work.

Hi all, I'm writing an interactive plotting function for viewing fMRI datasets. Currently, I get keypresses using grDevices::getGraphicsEvent(). Unfortunately getGraphicsEvent() only supports the X11(type="Xlib") graphics device on Unix systems. The Xlib device doesn't support buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots causes l...

Except from the change log: - Added support to schedule using at(1), see README.zfs-auto-snapshot.txt - take_snapshot will only run if option "manual" given or FMRI is online - added command line action "unschedule" - retry all jobs (at and cron) using a short term reschedule (AT_RETRY="now + 5 minutes") if they cant be run due to a temporary condition such as - smf service offline or uninitialized - pool being scrub...

Hi, I''ve just changed my debian preseed configuration to install the debian unstable package of puppet v0.22.1. As part of the preseed I have a late command that clobbers the /etc/init.d/puppet file into using the puppet standalone program and not the puppetd (as this is what I''m using). Since the upgrade to 0.22.1 every boot hangs during the initd. Going into standalone mode

I keep getting this error when I try to use the sem package. I and another person who has successfully used the sem package for similar analysis (fMRI effective connectivity) cannot figure out what is wrong with my code. I would appreciate any suggestions. The error message: Error in data.frame(object$coeff, se, z, 2 * (1 - pnorm(abs(z))), par.code) : arguments imply differing number of rows: 6, 0 In addition: Warning message: Could n...

Hi Helpers, Does anyone know how to read jpeg, bmp or png files into R? I have some photos of brain scans and I want to quantify some aspects of their size. I might be able to do this with the 'locator' function, if I could figure out how to read the files in and make them into an image that I can display on the R Windows device. I have experimented with readBin, using a simple

...nd variances) from both programs are nearly identical, but the model chi-squares (and significance estimates of the parameter estimates) are different. I am using Maximum Likelihood in AMOS. R I think defaults to two-stage-least squares estimate, and AMOS 16 does not implement 2SLS. I am using fMRI data, so the error variances are likely correlated, and the data non-normal to varying degrees. Is 2SLS the better way to go for these kinds of data? Is there a way to change the default method for R sem? I couldn't find this in the ?help. I note I have run some of the AMOS examples in R an...
