ERROR (SYS1): Model Load: Unknown Error

Hi Søren,

Thanks for your help in tackling my issue. I have taken your advice,
except for where you suggest excluding the human from the model and
then trying to get the environment up and running, I have done the
opposite. I am excluding the wheelchair for now, focusing solely on
the subject movement in space. Using the Runner example in the model
repository, I have successfully loaded all the markers, however now
that I am trying to attach the human to the markers, I have come up
with the following problems:

1.) Every time I get an error, even when it is something simple
like an unresolved object, the next time I run the model I always get
the following error (it makes no sense to me):
ERROR (SYS1): Model Load: Unknown Error

2.) If I then close out of AnyBody and re-start it, running the
model with the fix in it, the model compiles fine and I can continue
working. But I am finding I have to re-start the program every time I
need to correct a small error. Any idea why?

a. I am thinking that maybe I have an infinite loop or something
in my model because just to load the model generally takes over one
minute (60-80 seconds). Loading similar models tends to take about 5-
10, so there may be something wrong with mine…

3.) I have currently commented out the wheelchair wheel hub and
beam markers (because I am going to work on the environment once I
can get the model loaded). Setting up the body to be driven in space
is proving harder than expected – it is kinematically indeterminate
upon loading. I have 306 rigid body d-o-f, however only 276
constraints. I’m not sure where else I can “ground” my model to make
it kinematically determinate so I can get the model to load, which
brings me to my last question…

4.) Lastly, as I had mentioned in a previous post, the very
beginning and end of my file has marker dropout for about half a
second. How can I ever get the model to run in lieu of the fact that
the first couple of frames have two of my markers located at zero due
to dropout? I can never get my SetInitialConditions to run due to
this fact – am I incorrect in thinking this?

Suggestions would be much appreciated! I am uploading my model in
two parts (because it is large) under the title “TEST.zip,” and “text
files for TEST.zip.” Just unzip the text files and put them into the
TEST folder to get the complete model.

Looking forward to hearing back from you!

Thank you,

Hi Sarah

The reason why the loading take so long time is the size of your data files,
they are very big, the analog file itself is 20mb. This data has to be
parsed like the normal script and it takes some time.

I think that the size of your data file might be part of the problem with
the unknown error. I tried to look into your files and found that the
Pointprocessed file seems redundant all the data I could find where zero, so
I would recommend to exclude this file for now. When you are working on the
kinematics you can also exclude the analog data, this will make the model
load much faster, once the kinematics is resolved you can add this back in.
When doing so it might be a good idea to have a look in the file an exclude
parts which are not used, if any?

After having excluded these two file the model loads much faster and I was
not able to reproduce the unknown error.

In AnyBody Ver 3.1, the c3d file will be loaded directly without the need
for the converter; this will make the loading process much faster.

Is it necessary to analyse all 20 seconds? To reduce the amount of data I
would recommend reducing the dataset to a shorter timeframe.

Q3: I would recommend that you start by adding all drivers from the
freeposture model this will ensure that to you have a kinematical running
model.

1 change the mannequin values so that your model is close to the recorded
markers

2 add marker drivers for the pelvis, one dof at the time and remove drivers
accordingly, always keeping a running model.

3 once the pelvis motion is ok then move on further up the spine, and to the
arms many of the driver should be possible to harvest from the
WheelCairRancho model.

Q4: Concerning the question about the marker dropout you can just adjust the
tStart and tEnd to a period of time where your marker data is valid, you
will load in all the data but only make use of some of it.

Hope this helps you move on

Best regards

Søren
