Dear Ifeffit users, Sorry if it's an idiot question, but I'm in troubles when trying to work with my L3-Pb absorption data with Athena. I'm a beginner with the Ifeffit stuffs... Also, sorry if this report is not correctly posted, but I will try to give you the maximum information I can... Let's go. The data were taken at the Brazilian syncrotron laboratory, and the "important" data are in columns 3 (energy), 4 (Io) and 6 (It). The file is of the following form: "Data" "Hora" "Ponto X" "CION1(CURTA)" "CION3(Longa)" "CION2(Média)" "Det. D" "Translonga" "Transmédia" "Det. G" "Det. H" "Det. I" 04/02/04 12:32:51 12899.99 1671379 865008 1244452 0 0.658666 -0.363712 0 0 0 04/02/04 12:32:54 12901.16 1668799 863916 1242264 0 0.658384 -0.363215 0 0 0 04/02/04 12:32:57 12904.32 1661863 860550 1237862 0 0.658123 -0.363569 0 0 0 04/02/04 12:33:00 12905.99 1660709 860007 1237669 0 0.658059 -0.364045 0 0 0 04/02/04 12:33:03 12907.65 1656852 858657 1236381 0 0.657305 -0.364574 0 0 0 04/02/04 12:33:05 12909.82 1655818 858151 1236604 0 0.657270 -0.365344 0 0 0 04/02/04 12:33:08 12912.15 1655627 857952 1236890 0 0.657387 -0.365807 0 0 0 04/02/04 12:33:11 12913.82 1655763 858599 1238443 0 0.656715 -0.366308 0 0 0 When I try to open it, with the latest version (ifeffit-1.2.6) installed in a Windows XP computes, Athena says that the file has fewer than 10 data points. And the following message was trapped by Athena: Athena0.8.030warnC:\Arquivos de programas\Ifeffit\horae\stash\ATHENA.TRAPCODE(0x 3be700c) at athena line 1349 main::__ANON__('Use of uninitialized value in concatenation (.) or string at ath...') called at athena line 3658 main::read_raw('D:/meus documentos/LNLS/D04B-XAS 1832-03/data/B040006.DAT', '', undef, 'SCALAR(0x3a80b78)') called at athena line 3516 main::read_file(0) called at /PerlApp/Tk.pm line 340 eval {...} called at /PerlApp/Tk.pm line 340 Tk::MainLoop() called at athena line 1411 The files in the /examples/Athena folder open correctly. Do I need to "clean" the data, leaving only the desired columns, E, Io and It? Again, sorry if it's a dumb question and if the report is incomplete...
