Hello MricroGL users,

While I was converting my multi echo bold data to nifti I receive the following warnings:

Found 600 DICOM file(s)
Slices not stacked: echo varies (TE 14, 46.16; echo 1, 3). Use 'merge 2D slices' option to force stacking

Do I need to be worried about the outputs? It looks like MricroGL does convert my bold data into 3 separate echos plus the BIDS sidecars (json) and place them into the chosen folder snd I do not see any issues. But "adjusting for negative mosaicrefacq times" warning got me worried bit??
In advanced setting I only chose 1)ignore derived and 2D images 2)precise Philips scalling 

Has anybody had the same issue or successfully converted multi echo data with mricrogl before? I would appreciate any pearls of wisdom or reassurance.

Thank you,

Remy
