[ome-users] Opera scanner Flex files: bfopen very slow

[Sebastien Besson]

Hi Fetallah,

in general, the API documentation for Bio-Formats should be browsable via the Javadocs
which are located at:
http://ci.openmicroscopy.org/job/BIOFORMATS-stable/javadoc/ for Bio-Formats 4.4.x
or
http://ci.openmicroscopy.org/job/BIOFORMATS-5.0/javadoc/ for Bio-Formats 5.0.x

As Christophe already answered, setting setGroupFile(false) before calling setId(id) should disable
the file grouping. Do you think exposing this groupFile option directly in the top level bfopen would
be valuable for you?

Cheers,
Sebastien

Thanks Christophe, you made my day :-)

I suspected something as simple as that. Where can I find the complete documentation for bf objects ?

Thanks into advance,

Did you try setting setGroupFile(false) on the bf object?

Subject: [ome-users] Opera scanner Flex files: bfopen very slow

Dear All,

I have tried to load one flex file using the matlab function bfopen.
If the flex file is isolated in one directory, then the function reads it immediately.
However, if the file belongs to the plate directory with many flex files near it, then the loading take about 1.5 hours (not to say forever).
In fact, it does the following steps:

#
Storing well indices
#
Looking for other .flex files
#
Looking for files that are in the same dataset as Y:\SomeLocation\Meas_01(2014-01-09_17-02-50)\003003004.flex
#
Measurement files not found.
#
Making sure that all .flex files are valid
#
Grouping together files in the same dataset

...etc

The plate is huge indeed (about 20 Gigs of data).

Is there a way to force it to read only one specific file, without extracting the metadata from the whole plate ?

Thanks into advance,
