Dear People, Is the function numarray.concatenate supposed to work for character arrays? It doesn't for me. Do I need to write my own? Thanks in advance. Please cc me, I'm not subscribed. Faheem. In [17]: foo Out[17]: CharArray([['T', 'T'], ['C', 'A']]) In [18]: bar Out[18]: CharArray([['G', 'G'], ['G', 'G']]) In [23]: numarray.concatenate((foo,bar)) --------------------------------------------------------------------------- error Traceback (most recent call last) /home/faheem/wc/corrmodel/trunk/<console> /usr/lib/python2.3/site-packages/numarray/generic.py in concatenate(arrs, axis) 1018 arrs = map(_nc.asarray, arrs) 1019 if axis == 0: -> 1020 return _concat(arrs) 1021 else: 1022 return swapaxes(_concat([swapaxes(m,axis,0) for m in arrs]), axis, 0) /usr/lib/python2.3/site-packages/numarray/generic.py in _concat(arrs) 1000 convType = ufunc._maxPopType(arrs) 1001 except TypeError: -> 1002 dest = arrs[0]._clone(shape=destShape) 1003 else: 1004 dest = arrs[0].__class__(shape=destShape, type=convType) /usr/lib/python2.3/site-packages/numarray/generic.py in _clone(self, shape) 783 def _clone(self, shape): 784 c = self.copy() --> 785 c.resize(shape) 786 return c 787 /usr/lib/python2.3/site-packages/numarray/generic.py in resize(self, shape, *args) 854 self[offset:offset+olen] = self[0:olen] 855 offset += olen --> 856 self[offset:nlen] = self[0:nlen-offset] 857 else: # zero fill resized zero-length numarray 858 self[:] = 0 /usr/lib/python2.3/site-packages/numarray/strings.py in _copyFrom(self, arr) 217 me = self._byteView() 218 if self._itemsize <= arr._itemsize: --> 219 me[:] = it[..., :self._itemsize] 220 else: 221 me[...,:it._shape[-1]] = it error: copy1bytes: access beyond buffer. offset=8 buffersize=8
