  1. Dr. Thielicke was very kind and he helped me! Thank you very much!

  2. There is no Plural option (colour range like that in PIV1.2) in PIV1.4

  3. Hi, your program has been really helpful! Thanks

  4. Hi, I tried to use PIVlab1.41 to analyze my data, I need to use extractions to obtain strain rate from 300 frames, and during the processing the program keeps indicating "you dataset contains NaNs. A vector interpolation will be performed..." I need to manually kick if I want to proceed to the end and obtain the data. Any idea how to deal with this? Thanks a lot in advance!

    1. I had the exact same question, replying only to get follow-up comments sent to my mailbox

  5. hi, i have one question
    what is it doing reference the u component and v component?

  6. Can I run PIVlab on 12-bit pictures?

  7. Hi all,

    When I hit "Analyze" I get the following error message in the MATLAB dialogue screen:

    Error in>@(hObject,eventdata)PIVlab_GUI('AnalyzeAll_Callback',hObject,eventdata,guidata(hObject))
    Error while evaluating UIControl Callback.

    has anyone encountered this/know what is going on?

  8. Dear all,

    I have contributed a parallel version of PIVlab in FileExchange.
