What steps will reproduce the problem?

1.

2.Create & train dataset (see outpout)
Summary of 'dataset/proj/dataset_proj.fit' (120 samples total, 1 samples per 
image):
'Class label' (interpreted value) number of samples.
'0005'  (5) 10
'0010'  (10)    10
'0011'  (11)    10
'0014'  (14)    10
'0025'  (25)    10
'0038'  (38)    10
'0040'  (40)    10
'0046'  (46)    10
'0050'  (50)    10
'0064'  (64)    10
'0075'  (75)    10
'0093'  (93)    10
Class labels are purely numeric

ARGS : train params : ld50r0.5i10S800B0,0,800,350
     : test params : ld50S800B0,0,800,350i6f1

3. wndchrm classify -ld50S800B0,0,800,350f1 dataset/proj/dataset_proj.fit 
/root/conv-3.TIF
