Hello everyone,

I'm having trouble with the fiber tractography. The DKE_FT runs for about 80 mins and I end up getting the following error message:

Error using save
Can't write file ...\dki_FT.fib.

Error in dke_ft (line 337)
}
MATLAB:save:cantWriteFile

Also, when the program starts, it gives a warning that:

{Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 1.708888e-16.}
{> In getODF_FCN at 27
In dke_ft>(parfor body) at 227
In parallel_function>make_general_channel/channel_general at 870
In remoteParallelFunction at 31}

Can anyone help me find out why these errors are thrown?

Thanks,
Ehsan
