how to extract subarray of cell array based on logical condition?

Hi everyone, I have a cell array of the form (but with lots more data)...

'TS-G5-box11-001_0000_-0.0_May01.mrc'  'box11'  '001'  '-0.0'  'box11_tomo_001'
'TS-G5-box11-001_0001_2.0_May01.mrc'  'box11'  '001'  '2.0'  'box11_tomo_008'

I'm struggling with something that should be really easy, I want to be able to access a subarray that just shows everything that contains 'box11_tomo_001' or 'box11_tomo_001', is there an easy way to achieve this?

Cheers,

Will

Actually all you need is strcmp. Given:

C = {...
'TS-G5-box11-001_0000_-0.0_May01.mrc'  'box11'  '001'  '-0.0'  'box11_tomo_001'
'TS-G5-box11-001_0001_2.0_May01.mrc'  'box11'  '001'  '2.0'  'box11_tomo_008'};

>> idx = strcmp(C(:,5),'box11_tomo_001')
idx =
  1
  0

If you have multiple string that you want to match then ismember can be useful:
