This feature can be very helpful in assessing spikes or sudden movements made by subjects. Other softwares only allow you to play movies of DICOMs but Analyze4D can play movies of any major neuroimaging data format.

Use interactive zoom and pan to easily reach your voxel of interest. Save the current view and reload it any time. Reset the view and go back to the default view.

Currently you can choose region of interest in three different ways:

• Rectangular
• Polygon
• One Voxel at a time
• Circular (work in progress...)
• Free Hand closed polygon (work in progress...)

Overlaying a mask over functional data can be useful in guiding you to pick the right voxels for ROI analysis. Using this option you can overlay greymatter, white matter, CSF mask or any combination of many masks onto your functional data.

Use a slider to interactively change mask threshold from 0 to 1 and see the effect in real time.

Using AAL mask you can localize a particular brain region and confine ROI analysis to that particular region. Currently we have defined 116 brain regions. You can select any combination of these 116 regions to mask the functional data.

Just viewing voxel time course alone is not enough. You need to overlay your experimental design over these voxel time courses to see if the experimental manipulation is eliciting the right voxel response. Analyze4D lets you input your design matrix and overlay it onto the voxel time courses in a very intuitive way. You can add offset to the design matrix, add a new condition, delete a condition and delete all conditions. You input the design matrix in SPM style by specifying the onsets and duration for each condition.

This option can be useful when you are doing ROI time course analysis on completely raw data. This option lets you detrend and filter the time course of each voxel before averaging and displaying the average. This prevent any bias in the time course due to scanner drifts.

Analyze4D allows you to measure the x and y coordinates of two cursors which can be moved to any location on time course. This lets you to easily measure the peak values if need be.

This option can be handy when you have a very long voxel time course (in other words you have too many scans). You can interactively zoom and pan to clearly see the voxel time course.

You can import motion regressors in SPM style of as a Matlab structure and plot them. You can interact with them by turning any f the 6 motion regressors on or off. This lets you easily assess if there is any task related motion in your paradigm and if there is, in which direction.

Subtracting one EPI scan from the very next scan can be a very useful way of assessing motion between consecutive scans. The more motion there is, the more

And most important of all, if all this does not fulfill your requirements, then you can request new features-toggle and we will implement it for you, free of cost.
