Prediction error with libsvm

Question

[xoron1991]

I've just recently started using libsvm. I've been trying for awhile to train my features get the model and then do a prediction with corresponding features. I am using MATLAB for my execution and unfortunately after I run it svmpredict just returns the usage definition of it even after the training shows the model and iterations. And it also displays "Wrong input format at line 3".

My training data is like this

-1 1:60 2:32 3:17 4:6
-1 1:60 2:31 3:17 4:6
-1 1:63 2:35 3:16 4:7
-1 1:61 2:32 3:17 4:7
-1 1:59 2:31 3:17 4:6
-1 1:56 2:29 3:16 4:5
-1 1:54 2:29 3:15 4:5

and my testing data is something like this

-1 1:60 2:39 3:66 4:32
-1 1:58 2:40 3:65 4:29
-1 1:58 2:42 3:68 4:31
-1 1:58 2:41 3:64 4:32
-1 1:56 2:33 3:42 4:27
-1 1:56 2:34 3:29 4:18
-1 1:57 2:34 3:43 4:13
-1 1:58 2:38 3:57 4:19
-1 1:60 2:39 3:63 4:26
+1 1:55 2:35 3:72 4:31

Please help

Hi @xoron1991, I am also learning to use libsvm. I have a multifasta file and I have no clue on how to give it as input. Can you educate me on how to move forward with the multifasta file?
