paired data issue

[christoforos-dimitropoulos]

Hey everyone. I am trying to use this tutorial (https://immunarch.com/articles/web_only/v21_singlecell.html) in order to load my 10x TCR data in order to track clonotypes across seurat clusters (as shown at the very bottom of the tutorial) However I face specific problems, I provide here my code (seu_all is my seurat object and the idents of the object are set as clusters):

barcode_cluster<-Seurat::Idents(seu_all) immdata_10x <- repLoad("~/sc_repertoire/scRepertoire_c57bl6j/bl6_tcr_data",.mode = "paired")

== Step 1/3: loading repertoire files... ==

Any input would be appreciated, thanks a lot!

Hi @christoforos-dimitropoulos!

My name is Maria Volobueva, I am the developer of Immunarch. Thank you for using the package! Could you provide an example of the file you try to load, as we will be able to quickly identify the issues.

Hi @christoforos-dimitropoulos!

As an input I give the folder with the output of the 10x cellranger vdj pipeline.

@christoforos-dimitropoulos,

Please compress the folder that you were using as input for repLoad (~/sc_repertoire/scRepertoire_c57bl6j/bl6_tcr_data in your case) and attach it to the message, so we can reproduce the issue and help you out. You can also send the data to our tech support at support@immunomind.io.

Best regards, Maria

Hi I am having a similar issue, the headers look the same to me though in the attached file.

Hi, @mbartl13!

Thank you very much for providing the data! Looks like this format of column names is unknown to the parser. I will work to add the support for this format in the future versions of Immunarch.

Best regards, Aleksandr

Closing this issue for now. It will be implemented in the next version of Immunarch.
