How to Restore wfdb without reinstallation? #121

Closed sami10007 closed 8 years ago

sami10007 commented 8 years ago

I ruined my wfdb os x 10.11.4 with 0-9-10 by running wrong initialisation. I can reproduce bug #106 etc by the following

WFDB_PATH=['/Users/masi/Databases']; 
ECG=1; NBP=100; IBP=100; Resp=1; WFDBCAL=[ECG, NBP, IBP, Resp]; % TODO ask http://www.physionet.org/physiotools/wag/wfdbca-5.htm
debugLevel=5; networkWaitTime=1000; [isloaded,config]=wfdbloadlib(debugLevel, networkWaitTime); 
N0=1; rawUnits=1; % Physical units: base and gain already applied 
[sig, Fs, tm1]=rdsamp(strcat('mitdb/',num2str(patient)),channel,N0,rawUnits);

I restarted Matlab and the OSX but I cannot get wfdb back to its default. Running the above command ruins the system in such a way that not even restart restores the settings. It would be great to understand why doing such commands make changes to the system itself. I think this should not be the case.

How can you restore WFDB system?

These commands should not change your configuration (you are just defining variables in your local workspace). Looks like your configuration was corrupted prior to this.
