ref_image = spm_vol('meanfunc.nii');
source_image = spm_vol('T1_structural.nii');
x = spm_coreg(ref_image, source_image);
disp('Estimated transformation parameters:');
disp(['Translation: ' num2str(x(1:3)) ' mm']);
disp(['Rotation: ' num2str(x(4:6)*180/pi) ' degrees']);

% Coregistration with custom parameters
flags = struct(...
    'sep', [4 2], ...          % Optimization sampling steps (mm)
    'params', [0 0 0 0 0 0], ...% Starting estimates

    'graphics', 1);
x = spm_coreg(ref_image, source_image, flags);

% Apply transformation to update image header
M = spm_matrix(x);
MM = spm_get_space(source_image.fname);
spm_get_space(source_image.fname, M \ MM);

% Coregister multiple source images (e.g., other modalities)
ref = spm_vol('T1.nii');
sources = spm_vol(char({'PD.nii', 'T2.nii', 'FLAIR.nii'}));
for i = 1:numel(sources)
    x = spm_coreg(ref, sources(i), flags);

### Dynamic Plotly Data Loading and Plotting (JavaScript)

Source: https://github.com/spm/spm12/blob/main/help/plot.html

This script parses URL query parameters to dynamically load data and configurations for Plotly plots. It can load data from JSON files or execute external JavaScript files that define Plotly figures. It handles potential errors during data fetching and ensures the Plotly library is available.

```javascript
var queries = location.search.split("?")[1]; if (typeof(queries) === "undefined") { alert("No data!"); } var query = queries.split("&"); for (var i = 0; i < query.length; i++) { var datatype = query[i].split("=")[0]; var filename = query[i].split("=")[1]; var ext = filename.split('.').pop(); if (ext === "js") { var firstScript = document.getElementsByTagName('script')[0]; var js = document.createElement('script'); js.src = filename; var data = {}, layout = {title: ""}, options = {}; js.onload = function () { Plotly.plot("plotly", data, layout, options); } firstScript.parentNode.insertBefore(js, firstScript); } else { Plotly.d3.json(filename, function(err, fig) { if (err) alert("Could not read data!"); if (fig.layout === "undefined") { fig.layout = {title: ""}; } if (fig.options === "undefined") { fig.options = {}; } Plotly.plot("plotly", fig.data, fig.layout, fig.options); }); } }
