Error creating ArrowFiles : Character(0)

When running ArchR with default parameters (threads set to 1) and inputting the ArrowFiles command into the terminal to ascertain whether any ArrowFiles have been created I receive an error: Character(0). I have tried adjusting the parameters to TSS=1.47 and FilterFrags= 3848 - prompted by the following line in the log file:

Detected 2 or less cells pass filter (Non-Zero median TSS = 1.47, median Frags = 3848) in file! Check inputs such as 'filterFrags' or 'filterTSS' to keep cells! Exiting!

But received the same error.

Please advise. ArchR-createArrows-1895358aa063-Date-2023-04-17_Time-11-56-45.log

Warmly, Sahar Jamal

Hi @SaharBJ! Thanks for using ArchR! Please make sure that your post belongs in the Issues section. Only bugs and error reports belong in the Issues section. Usage questions and feature requests should be posted in the Discussions section, not in Issues.
It is worth noting that there are very few actual bugs in ArchR. If you are getting an error, it is probably something specific to your dataset, usage, or computational environment, all of which are extremely challenging to troubleshoot. As such, we require reproducible examples (preferably using the tutorial dataset) from users who want assistance. If you cannot reproduce your error, how will we be able to help? Before going through the work of making a reproducible example, search the previous Issues, Discussions, function definitions, or the ArchR manual and you will likely find the answers you are looking for. If your post does not contain a reproducible example, it is unlikely to receive a response.
In addition to a reproducible example, you must respond to the following questions before we help you, unless your original post already contained this information: 1. If you've encountered an error, have you already searched previous Issues to make sure that this hasn't already been solved? 2. Can you recapitulate your error using the tutorial code and dataset? If so, provide a reproducible example. 3. Did you post your log file? If not, add it now. 4. Remove any screenshots that contain text and instead copy and paste the text using markdown's codeblock syntax (three consecutive backticks). You can do this by editing your original post.

If I had to guess, you are using the wrong genome in addArchRGenome().
