Issues with Multipage TIFF Datastore

[nicost]

The script below - that should acquire 3 images, and put them in different positions in the datastore - results in the images being saved on disk, but not being retrievable: Only the last image (position) can be found. This is most dramatically illustrated in the viewer: it displays each new image as it is snapped, but at the end, only the last image is present. Setting the intended dimensions in the SUmmary Metadat does not make a difference. I do not understand why/how normal MDA acquisitions work. This problem does not exist in the RAMDatastore (did not test single page TIFF yet). A similar issue exists for channels, time pints and z-positions seem to be handled correctly.

//targetStore = mm.data().createRAMDatastore();

nrPos = 3;

cb = Coordinates.builder().t(0).c(0).p(nrPos + 1).z(0);
c = cb.build();
targetStore.setSummaryMetadata(targetStore.getSummaryMetadata().
									copyBuilder().intendedDimensions(c).build());
            
mm.displays().createDisplay(targetStore);

for (int i = 0; i < nrPos; i++) {
	imgs = mm.live().snap(true);
	cb.c(0).t(0).z(0).p(i);
	img = imgs.get(0).copyAtCoords(cb.build());
	targetStore.putImage(img);
	Thread.sleep(1000);
}

targetStore.freeze();

mm.scripter().message("Done");

Changing the first line to:

targetStore = mm.data().createMultipageTIFFDatastore("C:\tmp\test", false, false);

makes it work correctly.

Setting the last parameter (split by position) to true, results in only a single position being saved. Setting only the first parameter to true, works correctly.

This is a problem, but regretfully not the problem I was trying to address;)

More elaborate version of the test script:

dirName = "C:\\tmp\\test5";
targetStore = mm.data().createMultipageTIFFDatastore(dirName, false, false);
//targetStore = mm.data().createRAMDatastore();

nrPos = 2;
nrC = 4;
nrT = 2;
nrZ = 1;
cb = Coordinates.builder();

for (int p = 0; p < nrPos; p++) {
	for (int c = 0; c < nrC; c++) {
		for (int t = 0; t < nrT; t++) {	
			for (int z = 0; z < nrZ; z++) {
				imgs = mm.live().snap(true);
				cb.c(c).t(t).z(z).p(p);
				img = imgs.get(0).copyAtCoords(cb.build());
				targetStore.putImage(img);
			}
		}
	}
	Thread.sleep(1000);
}

targetStore.close();

mm.scripter().message("Done");
