@Louis1216 , I see that an invitation to join the Data Access team on 12/16. Once you click on the "Join" button, you will be able to access the data on the challenge website under the **Files** tab. --- @zndr27 , I have forwarded your question to the challenge organizers.
@vchung Does BraTS allow for commercial use? On the [Data Conditions](https://www.synapse.org/Synapse:syn51156910/wiki/622360) page I see the following: **Data Usage Agreement / Citations:** You are free to use and/or refer to the BraTS datasets in your own research, provided that you always cite the flagship manuscript (published or pre-published) resulting from the challenge, as well as the following challenge-specific manuscripts... However, there is no specific mention of the rules for commercial use. Could you point to the webpage / license that specifies this? Thanks, Zander
Dear @vchung I have also signed up for the challenge and submitted the data access form, but haven't received an email yet. Would you please let me know if there is anything further I should do? Thank you so much. My email is xuzhou.wu@monash.edu Best regards,

Hi @cmammola @cyunseo0320 and @zaid.auw , Apologies for the delay - I just checked the logs and invites were sent to your Synapse-registered emails dated yesterday. In the email will be a "Join" button. Once you click on that button, you will automatically be added to the team. Only after joining are you able to access and download the 2023 challenge data, accessible under the Files tab of the challenge website.
Hi @vchung, I've completed all the steps but still haven't received an email inviting me to join the Data Access Team. Any help would be really appreciated, thank you!

Hello, I requested the data access but I didn't get the email you're supposed to receive after 15 min. Can you help me? Thanks
@Danish_ali , The BraTS 2021 dataset is now part of the BraTS 2023 dataset under the [BraTS-GLI folder](syn51514105). As for your other data questions, they will be addressed by one of the BraTS challenge organizers.
@vchung, thanks for the information. I also want to get the Brats 2021 dataset but when i click on the registration form of Brats 2021 it displays that Brats 2021 is now part of Brats 2023. But i could not find anything related to Brats 2021 here. Also kindly let me know either in each new challenge previous challenge data is included or dataset in each new challenge is different from the previous one? Also guide me that what is the orientation of the 3D MRI images in Brats datset either it is axial, sagital or coronol?
@Danish_ali - Once you click on the "Join" button, you are automatically added to the team. Only after joining are you able to access and download the 2023 challenge data, accessible under the Files tab of the challenge website. The banner you mention is there to notify other users that one cannot directly request to join the team; it has to be with the Data Access form. Hope that helps!
Hi @vchung, I have completed all the steps and received the email to join the team once i click on join then i abled to join the team as my user name appears in the team member but data is not accessible still as i click on the join it redirectes me to member page and this dialogue appears "This team is closed to membership requests." Kindly guide how will i able to gest access to the data. Thanks
@Panchakshara - Apologies for the delayed response! If you are still experiencing issues gaining access, please let us know. @nafi007 - Once you click on the "Join" button, you are automatically added to the team. The banner you mention is there to notify other users that one cannot directly request to join the team; it has to be with the Data Access form.
Hi, I did all the steps as outlined but when I click "join" in the email that's sent out 10-15 mins after filling out the form I see the message "This team is closed to membership requests." . Also, do you provide the test set? (since I would like to compare the performance of my model with test scores of other models which have had papers published). If you don't provide a test set, does this portal still accept submissions to evaluate my model on the test set ? Thank you!
I have registered for the challenge and filled up the data access form using my username (Panchakshara). However, I still haven't received an email invitation. I request you to kindly look into the matter and make the data accessible to me.
@JiyaoLiu , Apologies for the delay! I just checked the logs and an invite was sent this morning (about 7 hours after your request). Let me know if you still did not receive the invite.
Dear, I have registered for the challenge, entered my username (JiyaoLiu) in the Data Access Google Form, as well as made sure the email on my profile is updated, but I still haven't gotten an email invitation to the Data Access Team. Please let me know if I'm missing anything else, thank you!
Hi @pilpel1 , I have confirmed that you are registered for the challenge and have joined the Data Access team, so yes, you should be able to access the challenge data - apologies for that! As a first step: when you go to the [Files tab](#!Synapse:syn51156910/files/), are you logged in as pilpel1?
To my best understanding I am registered, but I can't download. I just see key in the files folder
I received the invite and can access the data now. Thank you so much!
@ishitangupta, Apologies for that! I just checked the server and an invite should've been sent. Let me know if you did not receive one.

@Taurus , Apologies for the troubles. Did you click on the link in the invitation before joining the team? If so, that would explain the issue - you will need to join the Data Access team before you are able to download. Let us know if you continue to experience issues.
Hello, I filled Data Access form first and then tried to download the dataset, but then I got an email to register first and filled out the form again. I did the same but I still can't download the dataset. Please rectify the problem.

@suhas-synapse , Sorry for the inconvenience. According to the server logs, I do see that an invite was sent, but for some reason, this does not reflect on Synapse (which would explain why you are not able to join the team). That being said, it looks like another invite has been sent to your email. Can you try joining again?
Hi @vchung , Clicking the "join" button in my mail sends me to a page that says, "This team is closed to membership requests." Can I still access this dataset? The same message is visible on the team page as well.
@rodschermitg , Thanks for the notification - I checked the logs and an invite has been sent to your Synapse-registered email. Once you click on "Join" in the team invite, you will be able to access the challenge data. Let us know if you are still experiencing issues.
Hi @vchung, Is it still possible to access the BraTS 2023 dataset? I have already submitted the BraTS Data Access form, but haven't received any invitation email from Synapse yet. Kind regards, rodschermitg
Dear @vchung Is there any metadata of BraTS 2023? Because i have access to the data but i could not find them and on And does the data differ from BraTS 2021 and BraTS 2023? Thank you

@YoungJun , An invite to join the BraTS Data Access team was sent to your email on 11-08-2023 at approximately 6:30 GMT. You will need to accept the invite before you can access the challenge data.

Dear, I requested the BraTS dataset and received the link to join the Data Access Team. Clicking the link simply redirects me to the team it's page saying "This team is closed to membership requests." In my download queue it still says "Download Permission Required". How can I get access to the data? Kind regards, Sander
@JeroenBertels , Submission queues for evaluating segmentations are not available at this time. Once the challenge organizers have confirmed that evaluation can start again, we will post an announcement. Sorry for the wait!
@vchung Thank you for getting back to us so quickly! Great, I have access now :-) I just wanted to submit some results to the metastasis validation set (31 cases), but seems that the submissions are not open anymore. Any idea when you will open them again? :-) Jeroen

Thank you very much! @vchung I have successfully achieved the addimission for accessing the dataset.
@tktkiii , I just checked the logs and it looks like the invites were sent out this morning. Once you accept the email invite and join the team, you should be able to access the data! Let us know if you're still experiencing issues. @supro , You may be able to achieve faster downloading speeds by using the Synapse CLI: ```sh synapse get ``` The Synapse CLI can be installed alongside the Synapse Python Client with: ```sh pip install synapseclient ```
The data download process is extremely slow ~40KBps. Can we do anything about it to make it faster?
I have signed up for the challenge and entered all the required information, but still get an empty file when clicking on Access Data, have yet to get an email either. Is there another form that I still need to fill out? Thinks, Best wishes!
