How to add BioSig extension in EEGlab in Matlab? - matlab

I am working with EEGLAB in Matlab. Now i need BioSig Plugin to export dataset in EDF format.But unfortunatley with EEG extension management is not working . It shows warning message. Is there any other way to add BioSig plugin in EEGLAb??

You should be able to just download it (https://sccn.ucsd.edu/eeglab/plugins/BDFimport1.2.zip) and unpack it into the plugins folders (eeglab2021.1\plugins)

How to read .mat files in EEGLab?

I am trying to read SEED Dataset in EEGLAB. The files are in .mat format. I am getting the error as --- EEGLAB error in function pop_loadeeg() at line124.Output argument "accept" and maybe others not assigned during call to "F:eeglab2019\plugins\neuroscanio1.3\loadeeg.m>loadeeg".
How to read the .mat file of EEG SEED Dataset in EEGLAB ? Please guide.
I hope this help:
Run eeglab.m, next in the pop up window: file->import data -> using EEGLAB functions and plugins -> from ASCII/float file or Matlab array.
Almost you can check the tutorial in the official EEGLAB page.

How can I create in Gehpi directed tree graph instead of sphererical

I want to make a network graph which shows the distribution of our documents in our folder structure.
I have the nodefile, edgefile and gephi graph file in this location:
https://1drv.ms/f/s!AuVfRBdVHkO7hgs5K9r9f7jBBAUH
What I do is:
Run the algorithm ForceAtlas2 with scaling 10-20, dissuade hub marked and prevent overlap marked, all other standard setting.
What I get is a graph with groups radial/spherical distributed. However, what I want is a tree directed network graph.
Anyone know how I can adjust Gephi to make this?
Thanks!
I just found a solution.
I tested the file format as shown on the Yed site "import excel file" page
http://yed.yworks.com/support/manual/import_excel.html
This gave me the Yed import dialog (took a life time to figure out that it's a pop up menu and not selectable through the standard menu)
Anyway, it worked and I've adjusted the test files with the data prepared for the Gehpi. This was pretty easy, I could used the source target ID's etc. Just copy paste.
I load it into Yed and used some directed and radial clustering algorithms on it. Works fine!
Below you can find the excel node/edge file used to import in Yed and the graph file you can open with Yed to see the final radial result.

Only thing to figure out is how to combine the weight (which represents the number of documents) with the node size.
Unfortunately, as of version 0.9.0, Gephi no longer supports hierarchical graphs. Maybe try using a previous version?
Other alternatives involve more complex software, such as Graphviz, but you need a .dot file instead of your .csv. I looked all over, but could not find an easy-to-use csv to dot converter.
You could try looking at d3-hierarchy, a node.js program, but then again you need to use the not-so-user-friendly npm. If you look at the link, it looks like it can produce the kind of diagram you're looking for.

Can't find 'Build.xml' after export Antenna files

I have made a J2ME program. This program will be used in 3 specific countries and has to support 7 different screen resolutions.
At the moment I have created 7 different builds for each resolution type and 3 variants in each for each of the 3 countries.
I am using LWUIT as my UI framework. I have configured MTJ with the following.
antenna-bin-1.2.1-beta.jar
WTK2.5.2_01
proguard4.8
on Eclipse 3.7.2
In the package explorer i right click on my project directory
select 'Export' (I couldn't find 'Export Antenna Build Files' under the 'Mobile Tools for Java' option)
I wait for it to do its thing.
I open the project folder and search for Build.xml. But can't find anything .
I find a folder called 'mtj-build' that contains another folder(custom-tasks) and two files mtj-build.properties and mtj-build.xml .
I want to able to write a build file that would be able to do the following
put in the correct resources according to the resolution its building
put in the correct theme according to the resolution its building
set the relevant attributes in the Application Descriptor file for each country
repeat this process automatically for each resolution and each country and place the respective .Jad and .Jar files in a particular folder structure as shown.
MainFolder:
{
Country1:{
Res1,
Res2,
Res3,
....},
Country2:{
Res1,
Res2,
Res3,
....},
Country3:{
Res1,
Res2,
Res3,
....},
....etc}
}
As I understand to do this I would need to set up a Build.xml. But then I can't find Build.xml after selecting the Export Antenna Build Files option.
How do I achieve this goal? Is it even possible to do this? Please do help . Thanks in Advance
===================UPDATE TO THIS POST #1======================
Follow the links mentioned by Eugen Martynov below.
on a side note: The reason I wasn't getting the option to Export Antenna Build files on the right click of the project was because they were referring to a customized version of the Eclipse IDE called Pulsar Eclipse.[ http://www.eclipse.org/pulsar/ ]
The Antenna build xml file generated by it is far more optimized than the one you get out of the standard Eclipse. I dunno why that is. But thats my Observation.
===================UPDATE TO THIS POST #2======================
Thanks for your suggestion Eugen. I will be writing a few sub Ant Build files to simplify my problem. I still have to figure out how to break this down.
Thanks for the link Telmo Pimentel Mota. In my current build I have 'wtkbuild' and 'wtkpackage'. And the build is working great. I just now have to figure out how to call or execute one build file from another following Eguen's suggestion.
I wouldn't give you complete answer but I give you way to find out it yourself.
Here about ant and building process. Here is building j2me with antenna. There are also should be examples of build.xml files in antenna sample folder. Here is alternate example about ant and building j2me without using antenna.
In your case you have to use different res folders and set different manifest options based on two additional properties country and resolution. You could pass properties outside build.xml by using properties file or by command line:
ant -f <path to build.xml> -D<property name>=<property value>

Weka EM cluster get "Error: Could not find or load main class test" in eclipse

I want to use weka to cluster tweets in the database in JSP. In GUI, I find only HierarchiccalClusterer and Filteredcluster available for string clustering. Then I find this clusteringdemo sample code from weka official website: https://svn.scms.waikato.ac.nz/svn/weka/trunk/wekaexamples/src/main/java/wekaexamples/clusterers/ClusteringDemo.java
However, after set up the sample arff code in weka directory, I get this error "Error: Could not find or load main class ClusteringDemo".
Can anyone help me to find out the reason?
I only change filename in the sentence data = DataSource.read(filename);. Besides, my classpath set up correctly for I already done some classifier.
1.- Maybe the ClusteringDemo.class is not in your classpath.
You should add the class of jar file to your project.
2.- Anyway, you can download the java code from: http://weka.wikispaces.com/file/detail/ClusteringDemo.java
Compile and run it (make sure that weka.jar is in your classpath).
3.- If you have added ClusteringDemo.java to your project. Make sure that it has the "package" line (the first line) according to its location. Otherwise Java will not be able to find it.
Good luck using EM, maybe you can also try N-grams + Naive Bayes.
