Hi everyone,  
When I use the PPMI database, I find that the data imaging protocols are partially different, for example:  
（1）Acquisition Type=2D; Field Strength=3.0 Tesla; Flip Angle=90.0 degree; Gradient Directions=30.0 ; Manufacturer=SIEMENS; Matrix X=128.0 pixels; Matrix Y=128.0 pixels; Matrix Z=2640.0 ; Mfg Model=Prisma; Pixel Size X=2.0 mm; Pixel Size Y=2.0 mm; Pulse Sequence=EP; Slice Thickness=2.0 mm; TE=80.0 ms; TR=10000.0 ms;  
（2）Acquisition Type=2D; Field Strength=3.0 Tesla; Flip Angle=90.0 degree; Gradient Directions=30.0 ; Manufacturer=SIEMENS; Matrix X=128.0 pixels; Matrix Y=128.0 pixels; Matrix Z=2640.0 ; Mfg Model=Prisma; Pixel Size X=2.0 mm; Pixel Size Y=2.0 mm; Pulse Sequence=EP; Slice Thickness=2.0 mm; TE=90.0 ms; TR=10400.0 ms;  
（3） Acquisition Type=2D; Field Strength=3.0 Tesla; Flip Angle=90.0 degree; Gradient Directions=30.0 ; Manufacturer=SIEMENS; Matrix X=1152.0 pixels; Matrix Y=1152.0 pixels; Matrix Z=33.0 ; Mfg Model=Prisma\_fit; Pixel Size X=2.0 mm; Pixel Size Y=2.0 mm; Pulse Sequence=EP; Slice Thickness=2.0 mm; TE=80.0 ms; TR=10000.0 ms;  
Can these data be used together for FBA analysis?  
Thank you very much!
