A corrected version of PCSLOT, my program for sequence-slotting, is now available by anonymous ftp from geology.wisc.edu.
There were two programming errors in the previous version (v. 1.5) of PCSLOT. First, under certain circumstances, the program would stop prematurely during the sensitivity analysis. Second, certain input/output errors were not handled correctly. Both of these bugs have been fixed in version 1.5b.
Those readers who have been using PCSLOT v. 1.5 need only replace the main .EXE file and the READ.ME file. First establish contact with the INQUA Boutique for anonymous ftp. Ftp geology.wisc.edu (or ftp 144.92.137.14) and logon as anonymous with your own e-mail address for the password. Issue the command cd /pub/inqua. Type ls to see the directory. You want to take a binary copy of the self-extracting file PCSLT15Z.EXE. So type bin to set the data transfer to give you an exact image of the original. Then type get PCSLT15Z.EXE. When you get the file on your own IBM/Clone PC, typing PCSLT15Z PCSLOT15.EXE READ.ME will extract just the changed files; new users should type PCSLT15Z to extract all the files.
I am working on version 1.6, which will have an option to produce the optimal matching of depths in Sequence (or Core) B relative to the depths in Sequence A. It will also produce output which will enable users to produce a variety of graphs illustrating the optimal slotting.
Version 1.6 should be ready by October 1994 or possibly sooner, and will be described in more detail in the January 1995 Newsletter. If you would like to be notified when version 1.6 is ready, please send me a message to that effect.
