MRSI fitting : no absolute quantification will be performed about fsl_mrs HOT 4 CLOSED

Hi Iurii,

Thanks for this bug report. I think I encountered this recently and thought I had fixed it, but I neglected to check the example data. Could you try updating to the most recent version (1.1.4) and try again? I was uploaded to the conda channel yesterday. I'll also look into this shortly.

Hi Will,
Thank you very much for your respond! I have update it to most recent version (1.1.4) but the problem still exist. Also I try it with wsl on Windows 10 but there I have even not able to use segmentation:

Hi @inokentiyTTT Thanks for confirming this. I've reopened the issue so it says on my radar. I'll take a look at this soon.

Hi @inokentiyTTT I believe everything should be fixed in version 1.1.5 which has now been released. Thanks again for the bug report.
