Hi,
I tried to use the palmer.extract() function, with no real success...
I had several error message during my first tries and manage to get rid
of them with a script like :
=======================================
runs = ['m1', 'm2', 'm3', 'm4', 'm5']
diff_tensor_Phi = 22.4
diff_tensor_Theta = -3.49
diff_tensor_Dratio = 1.22
diff_tensor_tm = 1.242e-08
for name in runs:
run.create(name, 'mf')
sequence.read(name, 'sequence')
diffusion_tensor.init(name, (diff_tensor_tm, diff_tensor_Dratio,
diff_tensor_Theta, diff_tensor_Phi), param_types=2,
spheroid_type='prolate', fixed=1)
palmer.extract(run=name)
name = 'aic'
run.create(name, 'mf')
sequence.read(name, 'sequence')
relax_data.read(name, 'R1', '800', 799.812 * 1e6,
'800_R1.dat_plus_sequence')
relax_data.read(name, 'R2', '800', 799.812 * 1e6,
'800_R2.dat_plus_sequence')
relax_data.read(name, 'R1', '600', 599.739 * 1e6,
'600_R1.dat_plus_sequence')
relax_data.read(name, 'R2', '600', 599.739 * 1e6,
'600_R2.dat_plus_sequence')
relax_data.read(name, 'NOE', '600', 599.739 * 1e6,
'600_NOE.dat_plus_sequence')
relax_data.read(name, 'R1', '500', 499.827 * 1e6,
'500_R1.dat_plus_sequence')
relax_data.read(name, 'R2', '500', 499.827 * 1e6,
'500_R2.dat_plus_sequence')
relax_data.read(name, 'NOE', '500', 499.827 * 1e6,
'500_NOE.dat_plus_sequence')
diffusion_tensor.init(name, (diff_tensor_tm, diff_tensor_Dratio,
diff_tensor_Theta, diff_tensor_Phi), param_types=2,
spheroid_type='prolate', fixed=1)
model_selection(method='AIC', modsel_run=name)
results.write(run=name, file='results', force=1)
=======================================
However, there is one problem still present : no model is chosen during
AIC selection... Here is what I get after the command
"model_selection(method='AIC', modsel_run=name)" :
=======================================
...
Instance 261.
Run Num_params_(k) Num_data_sets_(n)
Chi2 Criterion
The model from the run None has been selected.
...
=======================================
It seems the mfout (which are all located in their respective folder :
m1, m2 , m3, m4 and m5) are not loaded properly...
Do you have any clue about this issue ?
Also, is there a way of extracting information from a mfout with relax
without inputing any sequence, diffusion tensor, or data..? I thought it
would be possible to use palmer.extract() in a short script like this :
=======================================
runs = ['m1', 'm2', 'm3', 'm4', 'm5']
for name in runs:
palmer.extract(run=name)
name = 'aic'
run.create(name, 'mf')
model_selection(method='AIC', modsel_run=name)
results.write(run=name, file='results', force=1)
=======================================
Do you see anything I do wrong ?
Thanks !

Hi,
This is simple enough to do. The user function palmer.extract() will
extract all the data (well that used by relax) out of Modelfree's
mfout files.

Edward

Hi,
I have different model-free analysis that originated from the program
ModelFree (with results in a 'mfout' file).
I would like to know if there is a way of loading these data to proceed
to model selection by AIC using relax.
I there ain't any way of doing this, I'll turn to the palmer.py script
and start from the beginning...
Thanks !
Sébastien
