AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

It was actually in several places, most importantly imseq.c. There's now a new environment variable you can use to control the JPEG compression quality, AFNI_JPEG_COMPRESS. This can be set like other AFNI environment variables in a script, command line, .afnirc or in the AFNI GUI Edit environment plugin under the Define Datamode, Misc menu. The default is 95, but can be reset to any integer from 1 to 100. Lowering the quality level can make images blockier or cause ghosting.

The cjpeg program that AFNI calls can be used independently to change compression quality too. See cjpeg -help for more information.
