Hi All,

Has somebody experience with converting SPSS files into ARFF format? Do
you have scripts of syntaxes for this purpose?

A sample of an arff file:

@relation lymphography
@attribute 'lymphatics' { normal, arched, deformed, displaced}
@attribute 'block_of_affere' { no, yes}
@attribute 'bl_of_lymph_c' { no, yes}
@attribute 'bl_of_lymph_s' { no, yes}
@attribute 'by_pass' { no, yes}
@attribute 'extravasates' { no, yes}
@attribute 'regeneration_of' { no, yes}
@attribute 'early_uptake_in' { no, yes}
@attribute 'lym_nodes_dimin' integer
@attribute 'lym_nodes_enlar' integer
@attribute 'changes_in_lym' { bean, oval, round}
@attribute 'defect_in_node' { no, lacunar, lac_margin, lac_central}
@attribute 'changes_in_node' { no, lacunar, lac_margin, lac_central}
@attribute 'changes_in_stru' { no, grainy, drop_like, coarse, diluted,
reticular, stripped, faint}
@attribute 'special_forms' { no, chalices, vesicles}
@attribute 'dislocation_of' { no, yes}
@attribute 'exclusion_of_no' { no, yes}
@attribute 'no_of_nodes_in' integer
@attribute 'class' { normal, metastases, malign_lymph, fibrosis}
