Attempted to read samples that are no longer available

Remember to change the format at which you write to the excel document (from previous forum we discussed). When I look at the express VI in your queue loop it's only set to 400 Hz, not 20kHz or 10Hz, where are you getting 20kHz or 10Hz from?

Hi, sorry abou this.

   For any samping rate, the data I acquired has only 10Hz samping rate.

I have changed the format at which I write to the excel document. Thank you for your reminding.

If you look at the waveform in LabVIEW before you write it to disk does it look right? The issue you are having might be with how MATLAB is reading in the file.

the waveform in LabVIEW before I write it to disk looks wrong also! But if I use the same loops without the queue, it looks right.

Do you think there is something wrong with the queue?
