Fiji plugin - does not support latest VS120 file format
Full FIJI for processing and quantitation:
- Get full FIJI from http://fiji.sc
.vsi with: File --> Import --> Bio-formats - (uncheck all Import
- FIJI - Fiji uses its own local and dedicated Java installation
(and is not such a security risk as the
Windows installed version which hooks into web browsers, etc.
Windows JAVA is not required by FIJI and can be deleted - a good
security practice if it is not needed by other programs).
- Checking the Java version
- You can tell which Java version ImageJ is using by clicking
the ImageJ status bar (below the square tool buttons) and looking for the part that says e.g.
"Java 1.8.0_66 [64-bit]". The relevant number is the one after
"Java 1."—so e.g. "Java 1.8.0_45" or similar indicates Java 8,
while "Java 1.7.0_79" or similar indicates Java 7.
- The current Java version validated for FIJI is 8.0.66
[viz. 1.8.0_66 on double click] as of 2018-01-26
- If Java is older than version 8, then it can be updated
be getting latest full FIJI installation from
http://fiji.sc and reinstalling
- ImageJ component - go to "Help --> Update Imagej ...".
Usually safe to do.
- Other components, e.g. FIJI, JAVA &
Bio-Formats - go to "Help --> Update ..."
- Hit "Manage update sites" button
and check "Java-8" and "Bio-Formats" and leave other
boxes as is
- Hit "Apply Changes" and then hot "Update
jars/ij-1.51s.jar" or similar
- Wait for downloads and restart FIJI
- Note incremental updates to the JAVA will be down
loaded and installed. Version updates (e.g. v6. to v8.) usually require
the whole FIJI installation to be reinstalled using the
latest download from http://fiji.sc
- Note the Java update on the Windows task does not
apply to the JAVA installation used by FIJI
- Note: a large number of user images and other user
added directories under the Fiji.app directory can
substantially slow down updating. Move such user
files to another directory.
- The current Bio-Formats seems to only open the largest
image in the .VSI file set
- 64 bit FIJI is usually required to open .VSI files due to
their large size.
- If image is large and computer bogs down, try cropping image
into smaller regions
- In "Edit --> Options --> Memory & Threads..." set "Maximum
memory:" to ~1 GB less than installed physical memory on your
computer, and uncheck "Keep multiple undo buffers"
- Progress bars are minimally present. Many times
nothing seems to be happening when there is processing quietly
occurring. Windows "Task Manager" "Performance" tab will
give an indication of activity and clues as to when to abort and
- Working with these large files can be tedious. An
alterative is exporting images as .TIF files on the VS120
computer. Note .TIF files need to be under ~1GB to be
openable in most programs. .JPEG2000 is a good alternative
format. Pixel size (e.g. um/pixel) needs to noted before
