Answer: A: Adding UMAP coordinates to metadata
... In Seurat 3, you can export the coordinates to a dataframe using `Embeddings()`. `umapCoord <- as.data.frame(Embeddings(object = AD007[["umap"]]))` You can then add the PC columns to the `meta.data` as you please (`cbind`, `sapply`, `paste(..,collapse=)`,...) For example, if you only need to ...

Comment: C: Converting this matrix to a binary matrix
... The problem with that is that you won't be able to know which GO term that `log2FC` is associated to. If you look at your example, `PTK2` has multiple `1s`, but only a single `log2FC`. With `dcast` you have `NaN` if the gene is not enriched and a `logFC` value (specific for that GO term) if it is. ...

Comment: C: Converting this matrix to a binary matrix
... dcast fills the table with what is passed by `value.var = `. The data specified in your question has only 3 columns, so the only value that can be used to populate the table is `log2FC`. Which value you want the table to be filled? what are the 0-1 values in your last table? ...

... You can convert a long table to a wide one with dcast library(data.table) dcast(yourDF,Gene_Name~GO_term , value.var = "Log2FC",fun.aggregate = mean) You may want to change the aggregate function depending on how you want to handle duplicated values. ...

Comment: C: Automation for Energy Minimizing protien structure
... bash is your friend here :D I would suggest to have a look at github as there are several gromacs wrappers (e.g. GromacsWrapper). If you need inspiration to write your own piece of code, you can have a look at the project I used. Note that **it is massively outdated**: [doitGROMACS_equilib][1] ...

Comment: C: Automation for Energy Minimizing protien structure
... It depends a bit where your mutations are. The topology of your 100 proteins are likely to be exactly the same, but for few residues. You can generate the topology for the wild-type and then replace the coordinates of the mutate residues, to obtain all the mutants you want. The quickest way could b ...
