I have a file that looks like this

>SEQ1
-----I--RL--AAIDVDG-NLT----------D--R--D-RL-ISTKA-IESIRS--A-
-E-K--------K-GLT-VSL----LS------GN-V----I-PVV---YA-L------K
IF---------------L-----GINGPVF------------------------------
>SEQ2
-MKI----KA--ISIDIDG-TIT------YPN-R-------MIHEK--A-LEAIRR--A-
-E-S--------L-GIP-IML----VT------GN-T----V-QFA---EA-A------S
IL---------------I-----G----TS-----------------GP-VV--------
>SEQ3
--KI----KA--ISIDIDG-TIT------YPN-R-------MIHEK--A-LEAIRR--A-
-E-S--------L-GIP-IML----VT------GN-T----V-QFA---EA-A------S
IL---------------I-----G----TS-----------------GP-VV--------
---AE--D------GG---A---------------------------------------I

The lines starting with '>' are the headers and the series of letters and dashes underneath each header is the 'sequence' associated with that header. I would like to split this data so that the header is one element in the array and the sequence data underneath is in another so - for example

element[0] = >SEQ1
element[1] = -----I--RL--AAIDVDG-NLT----------D--R--D-RL-ISTKA-IESIRS-
+-A-
-E-K--------K-GLT-VSL----LS------GN-V----I-PVV---YA-L------K
IF---------------L-----GINGPVF------------------------------

On first sight, it seems a fairly easy split operation, and I thought initially I could just split on new line, but I cant due to the sequence data occurring over several lines in the file. Any advise/thoughts on how I might be able to do this much appreciated. Thanks in advance.
