How to Restore wfdb Without Changing Directory in OS X?

[sami10007]

I want to restore wfdb without changing a directory in OS X. The first occurrence in the ticket #106. I describe some of its complications in #122. System: OS X El Capitan 10.11.4, WFDB 0-9-9 - 0-9-10.
I extended one issue of the thread to the deletion of the system in the ticket #124 because it will help me understand how to restore the system.

Case 1

I run wfdbdemo and I get

Reading samples ECG signal from MIT-BIH Arrhythmia Database
Error using javaObject
No class org.physionet.wfdb.jni.Rdsamp can be located on the Java class path

Error in rdsamp (line 114)
    javaWfdbRdsamp=javaObject('org.physionet.wfdb.jni.Rdsamp');

Error in wfdbdemo (line 12)
[ecg,Fs,tm]=rdsamp('mitdb/100',1,N);

It seems that the Java class path has changed. I run again to reinstall the system by Ikaro's default way

[old_path]=which('rdsamp');if(~isempty(old_path)) rmpath(old_path(1:end-8)); end
wfdb_url='https://github.com/ikarosilva/wfdb-app-toolbox/raw/master/wfdb-app-toolbox-0-9-10.zip';
[filestr,status] = urlwrite(wfdb_url,'wfdb-app-toolbox-0-9-10.zip');%Octave users may have to download manually
unzip('wfdb-app-toolbox-0-9-10.zip');
cd mcode
addpath(pwd);savepath

but I get the latter errors.

Idea - wfdbpath

I did not understand what Ikaro means in #120 with WFDB_PATH. My proposal is WFDB_PATH=['/Users/masi/Databases'];. Reproduction of the problem also in the ticket #117. Probably, understanding this would help to understand the problem of the thread.

Delete old System and Restore a New System

I deleted path/mcode directory and initiated the system again, but still, I get the error. I run wfdbdemo and get (also described in the ticket #106) the latter error again.

How can you restore WFDB Without Changing Directory in OS X?
Which directories should be removed here?

[ikarosilva]

1. If you want to change the WFDB path, you actually need to edit the file wfdbloadlib.m Specifically modfying the variable:

WFDB_PATH=['/Users/masi/Databases'];
And restarting MATLAB.

2. If you need to completely uninstall the toolbox, you will need to to remove the toolbox path ( from MATLAB's path. See:

http://www.mathworks.com/help/matlab/ref/rmpath.html

And restart MATLAB. You can see what is your Toolbox path by running:

[~,config] =wfdbloadlib
