Hi Fatameh,<br>
<br>
- In the LORETA program, you go to main utilities > Format
converter. <br>
- There you select: input binary file (sLORETA) <br>
- It does not matter which format for output you choose, I coded it
robust, it'll figure it out. As it says, rows are time points,
columns are the volume-gridpoints (called voxels)<br>
- After using loreta2fieldtrip the data is in normal FieldTrip
volume format, see here: <a
href="http://fieldtrip.fcdonders.nl/reference/ft_datatype_volume">http://fieldtrip.fcdonders.nl/reference/ft_datatype_volume</a><br>
<br>
To get familiar with FieldTrip source plotting etc, see the
tutorials, for instance: <a
href="http://fieldtrip.fcdonders.nl/tutorial/plotting">http://fieldtrip.fcdonders.nl/tutorial/plotting</a><br>
- The following steps are:<br>
1) create a template: template = ft_read_mri([cur_path_FT,
'\external\spm8\templates\T1.nii']);<br>
2) interpolate your volume on the MNI template: [interp_mean] =
ft_sourceinterpolate(cfg, GA_mean, template);<br>
3) plot it using ft_sourceplot<br>
<br>
Hope it helps,<br>
Ingrid<br>

<div> Hi Fatemeh,<br>
<br>
I had the same error recently when I did the same. I
filed the bug, see <a moz-do-not-send="true"
rel="nofollow" target="_blank"
href="http://bugzilla.fcdonders.nl/show_bug.cgi?id=2144">http://bugzilla.fcdonders.nl/show_bug.cgi?id=2144</a><br>
<br>
I did create a work around. In the LORETA program, you
can export the source data as a text file. You can
read that text file in with loreta2fieldtrip.m. It's a
bit of a patch, but it worked for me. <br>
<br>
Hope this helps,<br>
Ingrid<br>
