Hi Zhen,
<div><br>
</div>
<div>Short answer:</div>
<div>As a proposed solution you could try one of the following:</div>
<div>- either compile the missing file yourself, or</div>
<div>- get a more up-to-date version of the spm and/or fieldtrip code. </div>
<div><br>
</div>
<div>Longer answer:</div>
<div>More information can also be found here: <a href="https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fieldtriptoolbox.org%2Ffaq%2Forganization%2Femaillist_howtoask%2F&data=05%7C02%7Cfieldtrip%40science.ru.nl%7Cf08118f41ee2468e83a208dd6eb71544%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C638788454781001466%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=JUnOBcUeq7g%2BSC%2FXk0wZojd9QIw%2B2pGnNV0bsaVZGQo%3D&reserved=0" originalsrc="https://www.fieldtriptoolbox.org/faq/organization/emaillist_howtoask/">https://www.fieldtriptoolbox.org/faq/organization/emaillist_howtoask/</a></div>
<div>Typically, when encountering an error upon code execution, the output to the screen mentions in which line and function the error is generated, your message only included ‘….’ . For future reference it would be extremely helpful if you include this information
right away.</div>
<div>The error message says: “Mat2file.c not compiled”. This means that a piece of c-code, called mat2file.c has not been compiled, i.e. matlab tries to run a piece of compiled code, aka a mex-file (which probably is called mat2file.mexa64/mat2file.mexw64/mat2file.mexmaci64/mat2file.mexmaca64
etc). The exact file extension depends on the platform on which the code is to be executed.</div>
<div>Typically, many errors might be platform dependent, so it would have been helpful to have included this information right away. </div>
<div>The uncompiled function is part of the spm toolbox. Thus, the error you get is that your distro of spm does not contain the compiled code required for your platform. </div>
<div>Since errors often are dependent on the version of the software (and downstream toolboxes) that you are using, it would have been helpful to have included this information. </div>
<div><br>

<div>Good luck,</div>
