Alignment tool...

Can be used to align the slices of the opened dataset or to align two separate datasets. See details here.

Crop dataset...

Crop the image and corresponding Selection, Mask, and Model layers. Cropping can be done in the Interactive, Manual or using ROI mode.

A brief demonstration is available in the following video:
https://youtu.be/PQtpYUuJwG8

When the interactive mode is selected it is possible to draw (by pressing and holding left mouse button) a rectangle area a top of the image. This area can then be used for cropping.

The values for cropping may also be provided directly by enabling the Manual mode. It is also possible to do cropping based on the selected ROI. Use the ROI panel to make them.

The dataset can be just cropped (the Crop button) or copied to another buffer and cropped (the Crop to button). The multiple buffer buttons buttons located at the top of the Directory Contents panel.

The cropped datasets can be placed back to the original dataset using the Fuse into existing mode of the Chop image tool available at Menu->File->Chop images...->Import.... See more here.

Resample...

Resample image in any possible direction.

A brief demonstration is available in the following video:

Transform

Transformation of dataset: image and all other layers. The following modes are possible

A brief demonstration is available in the following videos:

Rotate: https://youtu.be/WFbZn0rfb5I
Transpose: https://youtu.be/PyEXX7j6pnc

Slice

Manipulations with individual slices of the dataset. The following actions are possible

Scale bar

Scale bar is a tool that allows to use a scale bar printed on the image to calibrate physical size (X and Y) for pixels in MIB.

A brief demonstration is available in the following video:

How to use:

Bounding Box...

Bounding Box defines position of the dataset in the 3D space; the bounding box information is important for positioning of datasets in the visualization software, such as Amira. The bounding box can be shifted based on its minimal or centeral coordinates. The current coordinates of the bounding box are shown under the Current Bounding Box text.

Attention! For 3D images the bounding box is calculated as the smallest box containing all voxel centers, but not all voxels as is! I.e. it's defined by the voxel centers, which means that a 1/2 voxel on both sides of the bounding box are subtracted, resulting in a bounding box that is 1 voxel smaller in all three directions.

A brief demonstration is available in the following video:

Parameter NameDescription
ScaleXThe physical size of pixels in X
ScaleYThe physical size of pixels in Y
ScaleZThe physical size of pixels in Z
xPosCentral position of the dataset in the X plane
yPosCentral position of the dataset in the Y plane
Z PositionMinimal Z coordinate
RotationRotation BIAS
Note!
Since it is designed for Gatan 3View system MIB adds 45 degrees to the detected rotation value

Parameters

Modifies parameters of the dataset: voxels sizes, frame rate for movies and units. Enter of new voxels results in recalculation of the bounding box.
