Missing write permission for project container

Install, Configure and Update
1

Hi,
I am trying to create a project in cryoSPARC, when I click the create project, it gives me the following error:
Unable to create project: ServerError: (‘create project error - could not validate arguments’, {‘slug’: ‘t20s-tutorial’, ‘valid’: False, ‘message’: ‘Missing write permissions for project container directory /data_processing3/users/zakia/tutorial’})

I recon it has something to do with multi users. I am sharing the PC with one lab mate, we have separate cryoSPARC account. It still wont let me create a project. What should I do to solve this?
P.S I am new to cryoSPARC and this the first time I am creating the project to follow the tutorial.

@Nishat CryoSPARC projects need to be created in a directory where the Linux account that operates the CryoSPARC software has write access (discussion). The person who installed or maintains the CryoSPARC software on the PC might be able to suggest or configure such a directory for you.

so we have user1 linux account, user2 linux account, and cryosparc linux account. In the cryospacr web server there’s user1 and user2 cryosparc account. I am user2.
When I loggin into the cryosparce web server with my user2 account, do I have to log in to the terminal as well? with the same account? or I have to log in to the terminal with cryosparc linux account?

Similarities between the user names associated with a Linux account and a CryoSPARC login, respectively, are coincidental. Irrespective of the CryoSPARC login, files created by CryoSPARC should be owned by the designated Linux account, cryosparc in your case.
The appropriate ownership and permissions of the container direcory depend on your specific compute environment as well as functional and security considerations. Please refer to the example (also posted earlier) for an illustration.
The solution in your case might involve

  • a project container directory on a suitably large and backed-up file system
  • a linux group that is associated with the container directory and that includes both your linux account and the cryosparc linux account
  • group write and sgid permissions on the container directory

Setting up these prerequisites may involve the linux shell and linux admin privileges. Once the container directory has been configured, logging on to CryoSPARC and processing data should not require terminal access.
