Matlab filter electical spikes in accelerometric data

Question

I have a dataset of accelerometric data that is affected by electical spikes.

I\'m looking for a good method to filter out or reduce these spikes as need to calcula

For others that may need this here's what I ended up using. Here's the data file data file link

Matlab filter electical spikes in accelerometric data

clear all, clc,clf,tic
aa=csvread(strcat('/tmp/example_data_with_peak.txt'),5,0); %will skip the first 5 rows that are text and zeros
figure(1);
plot(aa)
Af=aa;
% Thresholds
Tl = -mean(abs(aa))*10
To =mean(abs(aa))*10

% initialisation
[peaks_r,peaks_c] = find( Af < Tl | Af > To);
peaks = find( Af < Tl | Af > To);

counter = 0;

while ~isempty(peaks)
    peaks = find( Af < Tl | Af > To);
    try
        Af(peaks) = ( Af(peaks-1) + Af(peaks+1) ) / 2;
    catch
        if peaks(1) == 1
            Af(1) = 0;
        else
            Af(end) = 0;
        end
    end   
    counter=counter+1;
end
counter
figure(2);
plot(Af)
