Re: Cell population frequencies in HistoCat

Dear tc28,

Could you create an issue on https://github.com/BodenmillerGroup/histoCAT/issues describing the necessary workflow?

Right now the work around would be to export the CSV files for each (or merge all and export one CSV) and count the clusters outside histoCAT.

Re: Histocat - Differential cell neighborhood analysis

Dear Steve,

This is a pretty unique and tailored question. I will respond via email with your data example.

For the Clustergram, use the command: view(Delta)

Re: Histocat - Differential cell neighborhood analysis

Hi Steve, I would run tSNE + PhenoGraph on all samples and run neighborhood analysis (1) on 4 different disease states for comparison and on all disease states together. When you run all together, do you see hierarchical clusters enriched in certain cell-cell interactions? When you run them individu...

Re: histoCAT on Mac - tiny display fonts

Dear Stoh,

The only way to customize the font size is to change the properties in Matlab GUIDE:
1) Right click on histoCAT.fig --> Open in GUIDE
2) Click on the elements you would like to customize and select a larger FontSize

Re: Shannon Entropy to quantify cell heterogeneity?

Dear Steve, The paper is already published here: https://elifesciences.org/articles/31657 I am working closely with the t-CyCIF team to implement this and other spatial statistics methods into histoCAT. One metric that we have recently implemented is a sliding window approach to quantify cellular he...
