Cannot upload new data about ularcirc

[davhum]

Thanks for getting in touch. Can you confirm the naming of your Chimeric.out.junction file, it appears to be named 0.junction. If so please rename to sample.Chimeric.out.junction. Similarly your circExplorer output should be named from circRNA_know_sort_1.txt to sample.ce As you can see Ularcirc requires specific file extensions to recognise the data file. I need to put a fix in to catch if no file is recognised – this is most likely why it just closed down on you. Let me know if the file renaming solves the problem. Regards, Dave

Hi
Thanks for replying.
Renaming the file solved the uploading problem. I have another issue.
I'm using the C. elegans genome. I loaded the genome and refGene data.

Then I upload the Circexplorer2 output file using "sample.ce" as its name without any problem.
However, when I navigated to Gene_view panel, a warning message appeared.

I can build the BSJ table as below:

But when I chose one gene to show the transcript, another error appeared.

Can you help with this?
Thank you.

I suspect this might be a coding error relating to no FSJ file being present. As you aligned data with STAR would you mind uploading the SJ.tab.out file. To do this rename the SJ.tab.out to have the same file prefix (which in your case would be s1.SJ.out.tab).

Note you will have to upload both s1.SJ.out.tab and s1.ce at the same time. Therefore make sure both files are in the same directory/folder so that you can select them both.

Let me know if this fixes the situation as this will confirm that I need to put another checkpoint in code.

Hi David
Yes, it works after uploading the SJ.tab.out and Circexplorer2 file.
Thank you for your great help.

Have updated code which should catch filename errors.
