Is there a way to change the directory to the fragment file?

[chent5]

I have generate a signac object using the newest Signac version. After that, one folder associated with the directory to the fragment file has to be renamed. Is there a way to only change the directory to the fragment file for the signac object? Thank you so much!

Currently there is not any way to change the fragment file path (I could add this in the future). For now you should remove the old fragment object and replace it with a new one with the correct path (https://satijalab.org/signac/articles/data_structures.html#the-fragment-class)

Thanks a lot for your prompt response. The above link shows how to add a fragment object to a chromatin assay. Could you please show me how to remove the old fragment object?

You should be able to do it using:

tmp <- Fragments(object)
tmp[[<index_to_remove>]] <- NULL
object <- SetAssayData(object, slot = "fragments", new.data = tmp)

I'll try to add a function to do this in one step for the next release

Thank you so much!

Added UpdatePath() function and the ability to remove fragment objects by assigning NULL (eg, Fragments(object) <- NULL). This is available on the develop branch and will be added to the documentation on the website in the next release
