How do we submit results of task_02 of Learn2Reg 2021?

I am follwing the tast_02 of Learn2Reg2021. And, I had my results include three .npz that format in folder as following: submission/task_02/disp_0001_0001npz, ..., disp_0003_0003.npz

Errors that I faced when uploaded the zip file:
Failed evalutils.exceptions.ValidationError: The displacement field /input/task_02/disp_0001_0001.npz is missing. Please provide all required displacement fields.

Thank you, organizers.

Perhaps you should check the spelling and format of your submission. For example, it should be "task_02", not "task 02" or "task02"; and "disp_0001_0001.npz", not "disp00010001npz" or "disp0001_0001.npz". For your reference, https://learn2reg.grand-challenge.org/Submission/.

P.S.: I am not the challenge organizer.

Thank you, cwmokab or organizers. I will check again the spelling and format of my submission. And repy again if still have problem.

Thank you again.

Hi,

lately, grand-challenge.org deletes empty top level directories of submissions. We will update the evaluation to deal with this at the beginning of next year. Until then please just add a dummy.txt file in the submission directory.

Let us know if this workaround works for you.

Best wishes, Lasse

Thank you for your reply, I submitted many time( >10) but not complete yet. I tried to submit many time ( I checked carefully my shape or format, ...My files is not problem ( 3x96x96x104 for task 2 of Learn2Reg2021). Some time when I submite , your wedsite notication is " Preparing" or " Execule" and then the old error as below following: The error when submite: " Failed evalutils.exceptions.ValidationError: The displacement field /input/task_02/disp_0001_0001.npz is missing. Please provide all required displacement fields."

I am waiting your updatae at that time, please as soon as possible. Thank you very much.

Have you already tried the workaround posted above?

Best wishes, Lasse

Thank you for @Lasse's reply. " Until then please just add a dummy.txt file in the submission directory." "Have you already tried the workaround posted above?"

I also have not already submitted. Because I do not know how do I have the dummy.txt to submit?. It mean, the last time with the task_02 of Learn2Reg 2021, I had the disp_0001_0001.npz, disp_0002_0002.npz and disp_0003_0003.npz. And I submited with the error so now I will create the dummy.txt file again to submit again, right?

Thank you @Lasse, @ cwmokab and Organizers.

Excuse me, the csv file in this keypoints compressed package has six columns, which generally represent the coordinates of the x, y, and z axes. What do the first three columns mean?

Hi @yuanpenggkate I'm not sure which csv files you mean. However, it sounds like these are original corrfield CSVs that contain the x,y,z coordinates of the fixed image in the first three columns, and the x,y,z coordinates of the moving image in the last three columns.

Best regards, Christoph
