Haven't updated for a while.

Always want to install debian because of the NeuroDebian (http://neuro.debian.net/#how-to-use-this-repository).  Finally, I bought a 2 TB hard disk ($72 dollars) from Amazon.com last week and installed it in my home desktop.  Then, I installed debian OS in the new 2 TB hard disk.  My old Fedora can still be booted from the other hard disk.

The installation of debian OS was quite easy.  My motherboard's CMOS battery had problem.  It caused me a little trouble.  The debian system installation was very smooth.  I downloaded the smaller CD version ISO image since I would have internet support during the installation process.  I burend iso image to a writable CD.  Then, I booted my desktop with this burned CD.  It brought me right into the debian installation window.  The rest was like all other system installation.  I just simply followed the step by step instructions.  Bingo!  I got my debian system installed successfully.

So far, I like the way it works.  Still a lot of work to do though ... I need to install all the other software packages (FSL, AFNI, CTF MEG, MATLAT, ...etc).  More work ...

Ha Ha

All right, post some nice group pictures.

MEG: shall I love you? Rich data plus various ways to analyze. What's the best? Or establish my own.

Parametric methods

    * Dipole Fitting
    * Multiple Dipole Fitting
    * Extended Patch Fitting (To correctly model surface extent of current distribution)


Scanning methods

    * MUSIC--MUltiple SIgnal Classification
    * RAP MUSIC--Recursively Applied (RAP) MUSIC
    * LCMV--Linear Constrained Minimum Variance
    * SAM -- non-linear adaptive spatial filter (use time domain sensor covariance)
    * Vector beamformer
    * DICS -- use cross-spectral density covariance


Imaging methods
L1 Norm

    * MCE - Minimum Current Estimate


L2 Norm

    * MNE - Minimum Norm Estimate
          o Software:MNE-Suite
    * LORETA - Low Resolution Brain Electromagnetic Tomography
          o Probably everything you ever wanted to know is at this website by Pascual-Marqui
    * LAURA
    * dSPM - dynamic Statistical Parametric Mapping


Bayesian Approaches

    * sLORETA - standardized Low Resolution Brain Electromagnetic Tomography
          o Open PDF file with all technical details
          o Download the free academic sLORETA software


Something New

    * eLORETA - exact Low Resolution Brain Electromagnetic Tomography
          o Technical report (abstract & PDF file) at arXiv
          o Web pages with full technical report
          o Some eLORETA results

mne_opengl_test

Bingo!

My AC adaptor of the D-Link DI-624 router broken this week!

I decided to upgrade my wireless router.  I ordered D-LINK DIR-655 from Amazon.com (80 bucks - I'm an Amazon website fan - I watched that company stock went up from 65 dollars/share to 183 dollars/share).

Get back to the real issue here.  Tonight I can not get my Fedora to connect to the new wireless router.

I accidentally un-installed all the wireless-tools.  Even command line iwconfig did not work.  I got into trouble.  I went to my windows PC and downloaded wireless-tools-29-5.1.fc12.x86_64.rpm and wpa_supplicant-0.7.3.tar.gz.  Then, I transferred them to my Fedora computer through external hard disk since the internet and intranet did not work and my wireless router is on the first floor.  I was not planning to unplug my Fedora and carry that big guy to the first floor.  Anyway, it worked fine.  The rpm did not have Public Key.  I changed /etc/yum.conf and set gbgcheck=0. 

#sudo yum localinstall wireless-tools-29-5.1.fc12.x86_64.rpm 
worked magically. 

For wpa_supplicant-0.7.3.tar.gz, it contains source code.  I extracted it and went into the src folder.
#make
#sudo make install

You can use wpa_gui or command line.

See http://hostap.epitest.fi/wpa_supplicant/wpa_gui.html

I did not use the gui of wpa.  I opened Network Connections and build the new wireless. 




#ifconfig
The system worked.

Use wpa software: http://www.linuxforums.org/forum/red-hat-fedora-linux/99133-setting-up-wpa-wireless-connection.html

1)
#gedit /etc/wpa_supplicant/wpa_supplicant.conf


Ctrl_interface = /var/run /wpa_supplicant 

Ctrl_interface_group = wheel

Network = (
Ssid = "YOUR_NAME_SSID"
Key_mgmt # = "WPA-PSK"
Psk = "YOURPASS_OR_KEY"
)


2) make association
# wpa_supplicant -B -dd -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

wait a few seconds ...

3) #dhclient wlan0

This experience:
Commands:
#ifconfig wlan1 up
#iwlist wlan1 scan
#iwconfig wlan1 essid yournet
#iwconfig wlan1 key yourkeyinHex
#iwconfig

List the routes:
#netstat -r

Command line connect wireless:
#sudo iwconfig
#iwconfig wlan1 essid mynet key mykeyinHEX
#ifconfig wlan1 up
#dhclient wlan1
#iwconfig wlan1


Hope those will be helpful for someone who has the same problem as I do.

Albert Einstein's Quotes

Everything should be made as simple as possible, but not simpler.

E = M C2

Anyone who has never made a mistake has never tried anything new.

Science without religion is lame, religion without science is blind.
