How to set a time step in bioformat Matlab

[michel]

Can you control the time step between different images in Matlab using Bioformats java library?

Hi,

the time stamp of each plane of an image is stored in the DeltaT attribute of each Plane.

If you are reading from an image, e.g. to set the frame rate of an animation, you should be able to access it through the getPlaneDeltaT method. For instance using bfopen:

Code: Select all

data=bfopen(path_to_file);
data{4}.getPlaneDeltaT(0,0); % Read the time stamp of the first plane of the first series
data{4}.getPlaneDeltaT(0,1); % Read the time stamp of the second plane of the first series
...


If you want to set the time step instead, e.g. for synthetic images, you can use setPlaneDeltaT as follows

Code: Select all

metadata.setPlaneDeltaT(java.lang.Double(.1), 0,0); % Set the time stamp of the first plane
metadata.setPlaneDeltaT(java.lang.Double(1.1), 0,1); % Read the time stamp of the second plane
...
