MATLAB: Problem with regexp and split, and picking some cells

Question

I have the following input:

>> data(1).Header
ans =
AF051909 |392-397:CAGCTG| |413-418:CAGGTG|

I needed to save them to cells as {'392-397', 'CAGCTG'; '413-418', 'CAGGTG';}

I so I used regexp to do so with the following code:

struKm(1).trueBinding = regexp(data(1).Header,'\s\||\:|\|','split');

this returns:

>> struKm(1).trueBinding
ans = 
      'AF051909'    '392-397'    'CAGCTG'    ''    '413-418'    'CAGGTG'    ''

as you can see there are to empty cells and I tried to find out why they are there but failed.

I also tried to ignore that and continue to picking up the cell that I need for the rest of my code which is 'CAGCTG' and 'CAGGTG'. I have this code to pick them up:

[r1,r2] = ismember(struKm(1).trueBinding,set)

it return zeros.

Can someone help with two issues please?

Regards, A.

Answer 1

you can maintain your code and add a line code to remove empty elements

data='AF051909 |392-397:CAGCTG| |413-418:CAGGTG|'    
s=regexp(data,'\s\||\:|\|','split');  
s(cellfun(@(x) isempty(x),s))=[]
