RRA NAN result

[Maryam Ashkbous]

Hello
I am running RRA for a normal gait and using gait2354 model. but when running is completed my results show:

************************************************************
* Summary of Mass Adjustments to Reduce Residuals *
************************************************************
* Body adjusted: torso
* Mass Center (COM) adjustment: dx =1.#QNAN, dz =-1.#IND
* New COM location: ~[1.#QNAN,0.37044,-1.#IND]
************************************************************
* Recommended mass adjustments:
* Total mass change: 1.#QNAN
* ground: orig mass = 0, new mass = 1.#QNAN
* pelvis: orig mass = 11.7512, new mass = 1.#QNAN
* femur_r: orig mass = 9.28103, new mass = 1.#QNAN
* tibia_r: orig mass = 3.69938, new mass = 1.#QNAN
* talus_r: orig mass = 0.099781, new mass = 1.#QNAN
* calcn_r: orig mass = 1.24726, new mass = 1.#QNAN
* toes_r: orig mass = 0.216126, new mass = 1.#QNAN
* femur_l: orig mass = 9.28103, new mass = 1.#QNAN

************************************************************
* Average residuals before adjusting torso COM:

************************************************************
* Average residuals after adjusting torso COM:
* FX=1.#QNAN FY=1.#QNAN FZ=1.#QNAN
* MX=1.#QNAN MY=1.#QNAN MZ=1.#QNAN
************************************************************

************************************************************
* Final Average Residuals *
************************************************************
* After torso COM and Kinematics adjustments:
* FX=-79.9902 FY=-159.98 FZ=-79.9902
* MX=-99.9939 MY=-99.9939 MZ=-99.9939
************************************************************

does anybody know what does "1.#QNAN" & "-1.#IND" mean in my results? and how I can get a normal result?

Any help would be appreciated

I am getting the same error. I hope somebody can help us.

Thanks!

Hi!
I also recive similar message after running RRA... I suppose that NAN means Not A Number and IND indeterminate, but does someone know what can be the reason of such results?
