design matrix (in)dependent sample t-test in ft_freqstatistics
by Nenad Polomac 22 Feb '17

22 Feb '17

Dear Fildtripusers, I have some time-freq EEG data from 2 Groups (25 Patients and 25 Controls). There are 2 conditions in the paradigm. I would like to do dependent sample t-test to compare conditions within Groups. Also I need independent sample t-test between the Groups. We have some preknowledge about the effects, so we want to look in already defined sensors within certain frequency and latency (no multiple comparison problem). I have difficulties finding a solution for the design matrix in the ft_freqstatistics. I am not sure if this solution for dependent sample t-test is correct? nsubj=25; cfg.design=design(1,:) = [1:nsubj 1:nsubj]; cfg.design=design(2,:) = [ones(1,nsubj) ones(1,nsubj)*2]; uvar = 1; ivar = 2; For independent sample t-test I have no idea.I couldn't find solution on the Tutorial Documentation page. Any suggestion is greatly appreciated. Thank you in advance!

getting FieldTrip to build again
by Daniel Bergey 13 Feb '13

13 Feb '13

I'm working on getting FieldTrip to build. What approach would be most likely to be merged upstream? I'll concentrate there. Option 1: build against old OpenGL I have ugly patches to do this, mostly by specifying upper version limits in the cabal file. Ugly in that I introduce at least one exported function with GLfloat in the type, and I'm not sure how hard it will be to make that go away. Option 2: build against new HOpenGL This means accepting that all the rendering code needs GLfloat or GLdouble. It seems reasonable to keep all that in one module, and only export polymorphic functions which accept normal haskell types. There are many more design decisions to be made than for Option 1. For instance, where does the abstraction barrier belong? My current thinking is that tesselation shouldn't depend on OpenGL, so I'll need a data structure to hold triangles. STL export would use the tesselation code, but not the rendering code. Downsides include not taking advantage of OpenGL's compact formats for triangles, or else contaminating the triangle representation with knowledge of how OpenGL does things. I haven't thought yet about the equivalent abstraction for color information. Thanks, Daniel

FieldTrip 0.2.7 fails to compile in GHC 6.12.3

Dear, I am new to fieldtrip, and tried to get started with some basic ctf data (subject01.ds), but after following closely all the commando's given at http://fieldtrip.fcdonders.nl/getting_started/ctf, I get following unexpected error. I have no clue where it comes from. (the only thing I did differently from the manual was adding more fieldtrip subdirectories to the matlab path, because after running fieldtripdefs, matlab did not find ft_read_header) Can anybody help me with this error? thanks a lot, maarten >> ft_headmodelplot(cfg); using headmodel specified in the configuration using gradiometers specified in the configuration creating dipole grid based on inward-shifted head shape 642 dipoles inside, 0 dipoles outside brain spherical head model with 1 spheres java.lang.IllegalArgumentException: adding a container to a container on a different GraphicsDevice at java.awt.Component.checkGD(Component.java:1099) at java.awt.Container.addImpl(Container.java:1041) at java.awt.Container.add(Container.java:927) at com.mathworks.hg.peer.FigurePanel.assembleFigurePanel(FigurePanel.java:218) at com.mathworks.hg.peer.FigurePanel.reconstructFigurePanel(FigurePanel.java:143) at com.mathworks.hg.peer.FigurePanel.handleNotification(FigurePanel.java:88) at com.mathworks.hg.peer.FigureNotificationHandlerImpl.forwardNotification(FigureNotificationHandlerImpl.java:62) at com.mathworks.hg.peer.FigureNotificationHandlerImpl.handleNotification(FigureNotificationHandlerImpl.java:29) at com.mathworks.hg.peer.FigureAxisComponentProxy.construct(FigureAxisComponentProxy.java:89) at com.mathworks.hg.peer.FigureAxisComponentProxy.setVisual(FigureAxisComponentProxy.java:112) at com.mathworks.hg.peer.FigureHG1Mediator.setClientVisual(FigureHG1Mediator.java:135) at com.mathworks.hg.peer.FigurePeer.doSetVisual(FigurePeer.java:2399) at com.mathworks.hg.peer.FigurePeer.access$1100(FigurePeer.java:121) at com.mathworks.hg.peer.FigurePeer$24.run(FigurePeer.java:2411) at com.mathworks.hg.util.HGPeerQueue$HGPeerRunnablesRunner.runit(HGPeerQueue.java:228) at com.mathworks.hg.util.HGPeerQueue$HGPeerRunnablesRunner.runNotThese(HGPeerQueue.java:260) at com.mathworks.hg.util.HGPeerQueue$HGPeerRunnablesRunner.run(HGPeerQueue.java:276) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

Re: Bug #21 - patch
by Conal Elliott 06 Jul '10

Hi Maciej, I was cleaning up my email and discovered that I hadn't applied your patches (to FieldTrip and reactive-glut) or even responded to you. My apologies! And thanks for your efforts. I just read through your FieldTrip patch, and it looks like you changed FieldTrip's interface to use OpenGL floats instead of Haskell Float & Double. I'm reluctant to shift in that direction, as I would like OpenGL to end up completely hidden behind an elegant, Haskell-centric interface. My initial attempts to stay with Haskell types failed, due to a strange lack of exporting of some methods in the OpenGL library (preventing me from making instances for Float and Double). I've emailed Sven repeatedly about the issue, but his focus is elsewhere. Perhaps if he hears from others as well. I'd appreciate any other ideas for getting unstuck here.

Terrible difficulty installing relevant packages
by Søren Renner 15 Jan '10

15 Jan '10

I cannot install reactive or reactive-glut from Cabal. I cannot install them by compiling from darcs. I cannot install "yi" by either method. The unstable debian repositories, the cababl repositories, and the darcs source repositories cannot be used together. In general what happens is that darcs source installation fails because haskell base packages are not present in high enough versions. Yet I cannot install the base packages from darcs source. I DID get haskell and glut working, so I can run gears.hs. Please advise me.

Fwd: ColorComponent & VertexComponent
by Conal Elliott 01 Dec '09

01 Dec '09

I ran into an obstacle getting FieldTrip working with the new HOpenGL. Have requested help below. I could probably hack around this HOpenGL problem, but I'd rather keep FieldTrip simple & general, so I'm waiting to hear back before going any further. - Conal ---------- Forwarded message ---------- From: Conal Elliott <conal(a)conal.net> Date: Tue, Dec 1, 2009 at 10:48 AM Subject: ColorComponent & VertexComponent To: HOpenGL Liste <hopengl(a)haskell.org> I upgraded to the OpenGL 2.4.0.1, and found that it doesn't support Float as member of ColorComponent or VertexComponent. Not only isn't Float a declared member of these classes, but I'm unable to create (orphan) Float instances of either, since the methods are not exported. Could someone either add Float instances or export the methods so I can do it myself? Thanks, - Conal

Vector2(..) error
by Paul Keir 01 Dec '09

01 Dec '09

Hi all, I'm running under Windows XP/cygwin and have the Haskell Platform/GHC 6.10.4. I thought I'd have a look at FieldTrip. If I run "cabal install FieldTrip" I get an error (see below) relating to Vector2. Any advice? By the way, GLUT programs run OK; apparently now even without explicit library linking (ghc --make file.hs) Cheers, Paul ...

FieldTrip 0.2.4 conflicts with OpenGL 2.2.3.0
by Gregory D. Weber 05 Jun '09

05 Jun '09

After upgrading OpenGL, I tried to re-install FieldTrip 0.2.4 and encountered these errors, from GHC 6.10.1 on Fedora 10 Linux: [ 3 of 17] Compiling Graphics.FieldTrip.Vector2 ( src/Graphics/FieldTrip/Vector2.hs, dist/build/Graphics/FieldTrip/Vector2.o ) src/Graphics/FieldTrip/Vector2.hs:69:9: Duplicate instance declarations: instance Functor Vector2 -- Defined at src/Graphics/FieldTrip/Vector2.hs:69:9-23 instance Functor Vector2 -- Defined in OpenGL-2.2.3.0:Graphics.Rendering.OpenGL.GL.Tensor src/Graphics/FieldTrip/Vector2.hs:72:9: Duplicate instance declarations: instance Applicative Vector2 -- Defined at src/Graphics/FieldTrip/Vector2.hs:72:9-27 instance Applicative Vector2 -- Defined in OpenGL-2.2.3.0:Graphics.Rendering.OpenGL.GL.Tensor [root@squirrel]# ------------ Previously, I had installed FieldTrip 0.2.4 with earlier versions of OpenGL. I got some scary-looking warnings in the 'configure' step: Configure warns: Warning: This package indirectly depends on multiple versions of the same package. This is highly likely to cause a compile failure. package graphicsFormats-0.1 requires OpenGL-2.2.1.1 package GLUT-2.1.2.1 requires OpenGL-2.2.2.0 package FieldTrip-0.2.4 requires OpenGL-2.2.2.0 -- but I did have both those versions of OpenGL installed at the time, and it did work. Is my best move now to re-install OpenGL 2.2.1.1 and OpenGL 2.2.2.0, keeping OpenGL 2.2.3.0, or had I better remove the newest version of OpenGL and just keep the older two? I hope I'm not answering my own question here, in my previous post, about the desirability of moving FieldTrip away OpenGL -- however, I think people meant something more than version problems by that ;-) -- ___ ___ __ _ / _ \ / _ \| | | | Gregory D.
