If  you  want  to  conduct  Z-stacks  alongside  multipoint  imaging  it  is  better  to  use  relative  Z-stacks  in  the 
symmetric and asymmetric options.

Saving Data 

Whenever  you  use  the 

Capture

  button  you  will  need  to  manually  save  each  acquired  image  (ND  acquisition  can 

autosave). 

1.

 

Got to the 

File 

menu and save the image in 

ND2 format. 

This will store the complete setup of the microscope 

in the metadata of the image. Using the ND2 format also means that you can reuse the acquisition/camera/ND 
acquisition settings at a later date (see below for details).  

2.

 

Save your data to a folder on Datadrive E:/ and at the end of the session transfer your files to the network 
storage drive (N:/LiveCellData). 

Data is kept for a maximum of 1 week in the documents folders and 1 month 

on the network drive. 

 

3.

 

Instr

uctions on how to connect the network drive to your King’s 

computer can be found when you login to 

your PPMS account, go to documents and select the N drive access document.  

Reusing settings 

1.

 

When  comparing  images;  such  as  for  fluorescent  intensity  it  is 
important to keep the settings the same to enable a fair comparison. To 
re-apply  the  same  settings  from  an  image,  open  image  in  the  NIS 
software, right click and select 

reuse camera settings

 and 

reuse device 

settings

2.

 

You can also 

reuse ND setup

 for keeping the same settings in the ND 

acquisition window.  

3.

 

When  reusing  settings  check  the  Ti2  pad  and  the  camera  settings  to 
ensure that they have been applied correctly.
