Hola:
Ayer me encontré con un problema al intentar integrar un grupo de Bias, generando un error.
Después de varias pruebas he logrado repetirlo con un pequeño grupo de archivos.
Se presenta cuando se marca "evaluate noise" y Normalizatión es "No normalizaton"
En otras circunstancias el error no se produce.
Todo ello con Windows XP Home Edition
Adjunto un fragmento de lo recogido en Processing Console en las condiciones en que se presenta el problema, junto con otras en que no se presenta y el proceso finaliza correctamente:
