[daip] Problem between record length and block size, with READISK

[Belles Pierre-Emmanuel]

  Hello,

     While using the READISK procedure to load AIPS-format files onto my
new laptop (running on Leopard), I've got the following error message:
LOCALH> FITLD1: TAPIO: RECORD LENGTH   2688 INCONSISTENT WITH BLOCK SIZE
 2880
LOCALH> FITLD1: UVFDAT: ERROR READING TAPE. IERR=    10
LOCALH> FITLD1: ERROR     10 RETURNED FROM UVFDAT
LOCALH> FITLD1: Destroyed  1 extension files of type HI

The files were written with the WRTDISK procedure, while I was working on a
Linux machine. For some reason, WRTDISK wrote data blocks with only 2688
bytes, making the files unreadable by READISK (which seems to expect to
receive fits-format files, with blocks having n*2880 bytes). Strangely, this
only affects only some of my files, not all of them.

   I tried to change the "corrupted" input files and add extra bytes until
reaching 2880, using the task TCOPY. According to the help file, "TCOPY may
be used to insert missing end-of-file marks between FITS-format data sets".
But I got the same kind of error message:
LOCALH> TCOPY1: Task TCOPY  (release of 31DEC11) begins
LOCALH> TCOPY1: DISK OUTPUT VALID ONLY FOR FITS FORMAT, NOT RECORDS OF
 2688 BYT
LOCALH>         ES
LOCALH> TCOPY1: WARNING: NO files copied

    I tried to load the files on another laptop, with a former version of
AIPS. Same pb.

    If you have any suggestions on how to solve this pb, please, they are
welcome !

  Cheers
