FCS Express Knowledge Base
What is the compensation workflow in FCS Express?
There's a saying that if you ask 10 scientists about how they go about compensating their flow cytometry data, you will probably get 10 different answers.
In FCS Express, there are several different options and features to help tailor FCS Express to your workflow needs.
This page will help walk you through some of the most common scenarios we have seen from our customers.
Expand the scenarios below for more information on how to implement a workflow.
What settings are available in FCS Express that help define its behavior regarding compensation?
Expand
In FCS Express, there are flexible settings that will help you define the behavior of FCS Express toward compensation.
Whether it is through global FCS Express User Options or through the Layout Options for a specific layout, FCS Express offers the flexibility to fit into your workflow.
Please watch the video below for more information regarding these settings.
I would like to create a brand-new matrix in FCS Express and assign that matrix as the default matrix to use for all of my data or assign that matrix to specific data files..
Expand
FCS Express allows for the easy creation of a customized compensation matrix for your data.
A user has the ability to either use a matrix as:
- the default matrix within a layout so that the matrix gets applied to all of their data that is played through an FCS Express layout, or,
- a user can assign that matrix to a specific data file.
Please watch the video below for more information regarding this process.
I have tweaked the automatic compensation for a data file, and I would like to apply it to the rest of the data that I run through my FCS Express template.
Expand
If you have edited an existing compensation matrix and would like to apply this same matrix to other files that you would like to play through your FCS Express layout, this can be completed through a right-click and by setting the matrix as your Default.
Please watch the video below to fully understand this workflow.
There are 3 options in this regard:
- You can set your FCS Express User Options so that the global behavior in FCS Express is that no compensation is applied to data.
- This means that all new blank layouts that are created will inherit this setting.
- You can set the Layout Option for a specific FCS Express layout to use No Compensation, by selecting the None option.
- This means that any data that is imported into that specific layout will not have any compensation applied to it.
- Also, if your goal is to simply remove compensation that is applied within a specific plot, you can do so through that plot's Format > Overlays menu.
I have a simple 2-color uncompensated experiment and I do not have compensation controls. Can I manually create a compensation matrix for the parameters within a plot?
Expand
Yes. A compensation matrix that is specific for the parameters within a plot can be easily created through a right-click on that plot.
Please watch the video below for more information regarding this feature.
I compensate my data prior to acquisition and would like for FCS Express to use the matrix that I created during acquistion.
Expand
By default, FCS Express is configured to automatically apply the spillover matrix that was obtained for your data during acquisition.
In other words, FCS Express will automatically apply the same matrix that was used during acquisition, while providing you the ability to tweak the matrix if needed.
Please watch the video below to fully understand this workflow.
In FCS Express, a user can create a compensation matrix that uses a combination of different control types, such as cells or control beads.
This particular workflow can be easily done through the Data-Specific Gates feature in FCS Express.
Please watch the video below for more information regarding this option.
